The Sun is showering us with far more gamma rays than anticipated according to new measurements from a Cerenkov radiation detector in Mexico. The way those gamma rays are produced is very cool. Also cool: data continue to suggest a significant problem with the so-called standard model of particle physics. Muons are misbehaving, and it may suggest a fifth, previously undescribed and unknown, force of nature. Check out all that cool stuff, silly sponsors and trivia, and space news on this episode of Walkabout the Galaxy.

In this episode, I am joined by Elden Brooks. Elden was born into Mormonism and faithfully followed the religion throughout his life. However, as time went on, he began to question his beliefs, leading to a crisis of faith. He also developed a debilitating auto-immune disease that confined him to his home for a whole year, with no cure available. During this challenging time, Elden turned to audio books on spirituality and self-help, which opened his mind and expanded his awareness. Additionally, he had a transformative experience with a plant medicine journey that miraculously cured his disease. As a result of these profound experiences, he made the courageous decision to leave Mormonism and step away from his successful career in finance. Elden decided to pursue his true calling and started studying counseling. His aim is to provide support and help to others who may be going through similar challenges and seeking a more fulfilling path in life. Elden is also a co-host of a podcast called Mormon, Mystics and Muons, you can listen to it here: https://open.spotify.com/show/3dYn0w7iqfUczwnLpGVJVi?si=6jDwGMkHRSCb04UeduRtbg Books mentioned in the podcast: The Middle Passage: https://www.amazon.com/The-Middle-Passage-audiobook/dp/B000QCS24S Chris Bache: https://chrisbache.com/ Connect with Valentina: Website: soul-vale.com IG: soulvale

Multiplicity of TeV muons in air showers detected with IceTop and IceCube by Stef Verpoest. on Wednesday 30 November The IceCube Neutrino Observatory at the South Pole can provide unique tests of muon production models in extensive air showers by measuring both the low-energy (GeV) and high-energy (TeV) muon components. We present here a measurement of the TeV muon content in near-vertical air showers detected with IceTop in coincidence with IceCube. The primary cosmic-ray energy is estimated from the dominant electromagnetic component of the air shower observed at the surface. The high-energy muon content of the shower is studied based on the energy losses measured in the deep detector. Using a neural network, the primary energy and the multiplicity of TeV muons are estimated on an event-by-event basis. The baseline analysis determines the average multiplicity as a function of the primary energy between 2.5 PeV and 250 PeV using the hadronic interaction model Sibyll 2.1. Results obtained using simulations based on the post-LHC models QGSJet-II.04 and EPOS-LHC are presented for primary energies up to 100 PeV. For all three hadronic interaction models, the measurements of the TeV muon content are consistent with the predictions assuming recent composition models. Comparing the results to measurements of GeV muons in air showers reveals a tension in the obtained composition interpretation based on the post-LHC models. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.16970v1

Muons are handy things. The particles act as cosmic X-ray machines. They've allowed scientists to peer into volcanoes, pyramids, and other structures. They've also provided views of ocean tides and tsunamis. And in the past few years, scientists have used them to look into typhoons in Japan. The technique could help produce better forecasts for storms around the globe. Muons are produced when cosmic rays — particles from beyond the galaxy — slam into atoms and molecules in Earth's upper atmosphere. The collisions generate “showers” of many other particles. The muons almost never interact with other matter. But the rare interactions they do produce can help scientists map the material they've passed through — from ocean water to solid granite. Researchers set up detectors below typhoons that passed over Japan in 2016, '19, and '21. That revealed the three-dimensional structure of the storms. The scientists mapped warm, low-pressure air in the center of the storms, surrounded by colder, high-pressure air. The observations were provided in real-time, offering views that weren't available any other way. When combined with other observations, they provided some of the most complete pictures to date of what was going on inside big storms. So these cosmic X-ray machines could help scientists better understand all storms — and perhaps produce better forecasts of what they'll do.

Muons in showers with energy E 0 geq 5 EeV and QGSjetII-04 and EPOS LHC models of hadronic interactions Is there a muon deficit in the models? by Stanislav Knurenko et al. on Tuesday 29 November The paper presents data on the muon component with a threshold (varepsilon_{thr} geq) 1 GeV. Air showers were registered at the Yakutsk array during almost 50 years of continuous air shower observations. The characteristics of muons are compared with calculations of QGSjetII-04 and EPOS LHC models for a proton and an iron nucleus. There is a muon deficit in the models, at energies greater than 5 EeV. To make an agreement between experimental data and simulations on muons, further tuning of the models is required. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2208.00606v3

The discussion turns to what alien beings might look like, with Sara Seager speculating on the possible existence of "lowans." Lexman bursts into laughter, insisting that such creatures would resemble nothing so crude as humans. Seager counters with some entertaining speculation of her own, including the idea that giant, alien elephants might exist. Near the end of the conversation, Lexman and Seager discuss the feasibility and implications of quantum mechanics, a topic that proves far more challenging than either of them anticipates.

Muons in the aftermath of Neutron Star Mergers and their impact on Trapped Neutrinos by Eleonora Loffredo et al. on Monday 12 September In the upcoming years, present and next-generation gravitational wave observatories will detect a larger number of Binary Neutron Star (BNS) mergers with increasing accuracy. In this context, improving BNS merger numerical simulations is crucial to correctly interpret the data and constrain the Equation of State (EOS) of Neutron Stars (NSs). State-of-the-art simulations of BNS mergers do not include muons. However, muons are known to be relevant in the microphysics of cold NSs and are expected to have a significant role in mergers, where the typical thermodynamics conditions favor their production. Our work aims at investigating the impact of muons on the merger remnant. We post-process the outcome of four numerical relativity simulations, performed with three different baryonic EOSs and two mass ratios, considering the first $15$ milliseconds after the merger. We compute the abundance of muons in the remnant and analyse how muons affect the trapped neutrino component and the fluid pressure. We find that the net fraction of muons is between $30 %$ and $70 %$ the one of electrons, depending on the baryonic EOS. Muons change the flavour hierarchy of trapped (anti)neutrinos, so that muon anti-neutrinos are the most abundant, followed by electron anti-neutrinos. Finally, muons modify the neutron to proton ratio inducing variations of the remnant pressure up to $7%$. This work demonstrates that muons have a non-negligible effect on the outcome of BNS merger simulations, and they should be included to improve simulations accuracy. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.04458v1

Get in touch.AntiprotonsAntiparticles are everywhere. They're just part of life. The electron has its positron partner. Muons and antimuons are both routinely created in the upper atmosphere.  They're so familiar that we often just call them mu plus or mu minus. The antiparticle nature of mu plus just isn't that big a deal.If you've been paying attention to our series, you know we've talked about antiparticles quite a bit, at least in passing. Up and down quarks sometimes associate with anti-up and anti-down quarks to form pions. Other mesons like kaons form similar quark-antiquark pairs.It's fun to see composite particles made up from particles and antiparticles. The neutral pion - for example - is a bound state of particle/anti particle partners - uubar & ddbar - not unlike positronium: where an electron and a positron orbit each other like an atom. Of course, all these composite particles are unstable.Arguably what separates antimatter from antiparticles is finding a composite particle that is stable. Or at least really long lived. Something that looks and behaves like ordinary matter. Something like atoms.Enter the antiproton.Just like the proton, the antiproton is a tiny bag of subnuclear goo. Virtual pions and gluons and other quantum effects are all dressed up in the antiproton package around three valance antiquarks. That's two anti-up quarks and one anti-down quark.  The antiproton looks virtually identical to the proton - except that it has a negative electric charge.Like the proton, the antiproton has a mass of about 931 MeV. In fact, it's difference from the proton's mass has been measured, and at present it looks like they're the same up to less than one part in a million!In fact, everything they measure from the antiproton seems to to line up exactly with the proton. The magnetic moment - a measure of a little dipole magnetic field generated by the anti proton - still appears to be equal and opposite to that of the proton.AntihydrogenAnd yes, the negatively charge antiproton can pick up a positively charge positron and form an atom. Like hydrogen. You know, Antihydrogen! Antihydrogen has been studied and confirmed to look and behave exactly like hydrogen. The positron energy levels of thes anti atom and the associated electromagnetic spectra are all the same. Even the fancy, hyperfine splitting of those energy levels have been experimentally shown to be identical with ordinary hydrogen, at least up to experimental precision.Antiproton decayBy all observations so far, the proton appears to be a stable particle. If the proton did decay, it would be big news and a boon for folks looking to study physics beyond the standard model.The antiproton - so far as we can tell - is also stable.  Which is good - our theory is self consistent - but it does present the question: if they don't decay, then where are all the antiprotons in nature?!Sources of antiprotonsNobody knows why there's so little antimatter in the universe, but there definitely is some.Antiprotons impinge upon the Earth's upper atmosphere all the time. They're secondary cosmic rays that currently appear to be associated with super high energy protons smashing into gas and other material sitting in between the stars in our own galaxy. It's a by-product - in other words - of cosmic ray collisions. We can make them here on Earth too. The ALPHA experiment at CERN has an antiproton source made by smashing protons into iridium. The Tevatron at FermiLab had an antiproton source that used Nickel instead.The Tevatron was an interesting particle accelerator in that - unlike the LHC, which colliders protons together - the Tevatron collided protons against antiprotons, to give it a little extra boost in energy from quark-antiquark annihilation when those two, composite particles collided.The fact that there is so much more matter in the universe than antimatter means that antimatter is simply going to annihilate against any matter that it runs into. But how protons and antiprotons annihilate is a complicated issue.Antiproton annihilationElectrons and positrons annhilate cleanly into a pair of gamma rays. The antiproton and the proton do not cleanly annihilate. There is no easy, super clean signal  when they annihilate. They're composite particles. Worse, they're both really messy composite particles.Typically what happens when a proton meets an antiproton is that one of the quarks meets up with one of the antiquarks and interacts from there. All kinds of particles can come out, things like pions, more protons,  and other emissions from the subnuclear goo. The details all depend on how quickly those particles are moving when they meet each other.If they're moving slowly, their quantum clouds of subnuclear goo might overlap, and a pion might be exchanged. If they're moving quickly, like they were at the Tevatron, those antiquarks - who carry the highest fraction of the antiproton's momentum - will collide with the quarks in the proton, and all kinds of things can - and have! - come out.

This week: Brian Greene on why we're religious, physicists discover what's inside the Great Pyramid of Giza, switching on the Large Hadron Collider, Elon Musk buys Twitter, and what is the future of atheism?BRIAN GREENE LIVESTREAMWhy did our ancient relatives create art and ritual if it didn't help them find food?If you know anything about evolution, you'll know that ancient humans didn't like to waste much time or energy on things that weren't necessary for survival - things like hunting or building shelters. So why did they create beautiful trinkets or elaborate rituals?This is a question Darwin himself considered, and it's the topic of a whole chapter in Brian Greene's latest book Until the End of Time. Brian explains that the common belief that religion gave our ancestors might have helped them work and fight together.He also talks about the terror management theory of religion. It's the theory that religion offering people an afterlife helped our ancestors not be frozen in fear, thinking about their death 24/7.Brian talks about religion and other fascinating topics, including his theories on consciousness and his predictions for the next big steps in cosmology, in his recent talk with Progressive Forum - it's definitely worth a look!And, there's nothing like seeing events in-person, so come and see, or even MEET, Brian when we tour him across Australia and New Zealand this June! Tickets are at the link in our bio.PYRAMID PARTICLESEver wondered what's inside the Great Pyramid of Giza? Well soon we'll know, all thanks to subatomic particles called muons.Muons are the awkward cousins of electrons. Their mass is about 207 times as large as an electron's, making them able to pass through hundreds of metres of rock.Picture an electron like a bullet, and a muon like a cannonball. The cannonball can smash through walls while bullets get stuck. Other technologies, such as ultrasound, ground-penetrating radar and X-rays, can only penetrate a short distance from the surface, but muons can go further.It was thanks to muons that in 2017 scientists discovered a surprising hidden chamber inside the Great Pyramid. Now, as part of international project ScanPyramids, the detectors are back to scan the Great Pyramid from another angle. The team also plan on scanning other ruins such as the Mayan Chichen Itza in Mexico, and they've already started mapping out the inner workings of Mount Vesuvius using muography.We can't wait to see what they find!HADRON COLLIDERAfter a 3 year nap, the Large Hadron Collider was switched on last week to help explain why the universe exists.During its well-earned break, the LHC got pampered with some maintenance and upgrades, to prepare it for its third and most powerful experimental period. If all goes to plan, scientists at CERN will begin experiments in June.Run 3 is all about the elusive neutrino. Neutrinos are among the most abundant particles in the universe. They're the size of an electron, but have no charge, hence the name “neutrino”.The question is, what are the properties of neutrinos? We still know pretty much nothing about them. If CERN manages to solve the neutrino conundrum, then it will be a landmark moment and could help refine the Standard Model.The Standard Model helps explain the forces in the universe and how different fundamental particles fit together to generate the cosmos we call home. Neutrinos are also critical to understanding nuclear physics, from the fusion reactions that power stars, to the fission reactions that occur in nuclear energy reactors.Let's hope they solve the conundrum!MUSK BUYS TWITTERWill Elon Musk be a free speech champion or new tech overlord? That's what everyone's wondering now that he's the owner of Twitter.Musk has been critical of Twitter's moderation of speech, and within a day of his takeover, some high-profile banned users have been allowed back on the site. As for Donald Trump, Alex Jones, Milo Yiannopoulos, and even Azealia Banks and Tila Tequila (yes- they're banned as well!), it's not clear whether they'll get their accounts back.Elon has said that he hopes that even his worst critics remain on Twitter, because that is what free speech is about. But despite his wishes, many people are already announcing they're leaving Twitter.With Elon at the helm, Twitter users could also expect an edit button, and an open source algorithm, meaning they'd be able to view the code that curates what they see. Musk has also said that users should be able to see if their post has been promoted or demoted.So, do you think Elon will have a positive or negative influence ? Let us know in the comments!NEW LANDSCAPE ATHEISMWho was the first atheist?If you listen to the British philosopher Julian Baggini in his recent talk “Atheism Revisited”, the first open and proud atheist was actually a Catholic priest.His name was Jean Meslier, and while working as a priest in 18th century France, he came to see that the church was not helping the poor as they said they were, but were actually lining their pockets.After that, there was David Hume, a Scottish Enlightenment philosopher who is the hero of many atheists today.But long after that came the New Atheist movement, fronted by some of the thinkers we've toured here at Think Inc.: Sam Harris and Richard Dawkins.These thinkers popularised atheism, but did they go too far? According to Baggini, author of ”Atheism: A Very Short Introduction”, perhaps they were a bit too militant, and isolated people from the cause instead of creating a “coalition of the reasonable”, which could also include reasonable religious believers.Have a listen to his talk, and make up your mind for yourself. And if you want to learn more about different schools of philosophical ethics, come along to our course starting next week. Tickets are at the link in our bio.---That's all for this week. Don't forget we've got two Think Inc. Academy courses starting next week, and tickets to our upcoming Brian Greene tour can be found at the link in our bio.Sign up to our newsletter → bit.ly/think-sign-up

A very different story this week: using high-energy particles, originating from violent supernovae and supermassive black holes, to scan the insides of the Great Pyramid of Cheops. Physicists are teaming up with Egyptologists to check some tantalising results from 2017 thaty suggest there just might be a previously unknown cavity — an open space — inside the Great Pyramid. Could it be a new, hidden room? A vault filled with ancient treasure? Or just somewhere they kept all the heating ducts and old pain cans?

The sparse molecules near the top of our atmosphere begin the process of catching the energy of those energetic particles from space and transferring it into heat or muons. These cosmogenic muons that typically make it all the way down to the surface.Near the surface, the atmosphere is a lot thicker, but it's still just a collection of ballistic molecules bashing into each other at 1000 miles per hour. Some of those molecules hit us, and some hit the ground. We perceive these molecular impacts as air pressure. By contrast, cosmogenic muons are moving through this mess at over 600 million miles per hour. To those muons, the surface of the Earth is barely noticeable. They fly through a lot of things: hundreds of meters of rock, oceans, plants and animals before colliding or decaying. By contrast, those particles of atmospheric gas typically reflect off the surface of the Earth. Rocks just aren't that permeable to most gas. As we explained in the ALPHA particle miniseries, helium gas generated from radioactive decay deep within the earth collects underground, trapped by rocks.One thing gas can permeate is surface water.Quite a bit of our atmospheric gases get dissolved into the ocean. Oxygen in the air allows the fish to breathe too, once dissolved into the water so it can be picked up by their gills. Increased carbon dioxide levels also imply more CO2 gets put under water. When the water on Earth's surface freezes, as it might do near the polar ice caps, it traps some of that dissolved gas with it. This has been happening for millions of years, and until somewhat recently at least, that ice has been compounding. New ice forms above, pushing old ice down. This has resulted in a LOT of ice.In Antarctica there are areas where the ice is over four kilometers deep! That's miles of ice! Greenland also carries massive glaciers, two to three kilometers deep, built up in same fashion.The gases trapped in that glacial ice is a frozen relic of an older atmosphere. The deeper the ice, the older the dissolved gases. As the mixture of molecules in our atmosphere changes over time, it sets down a record in the glacial ice. The deepest ice, millions of years old, can tell us what the atmosphere was like millions of years ago.Extracting that ice is quite the scientific adventure!This all easy to say in theory - but the practice of Science requires a lot of gory, technical detail. Different measurements from different samples of ice at different depths from different parts of the world need to be calibrated.  Ice can form at different rates in different places under different conditions.But, at least averaged over a given year or decade or so, the atmosphere should be well mixed. Huge weather patterns around the world mix the air, ensuring should be about the same. And so the Scientific logic goes like this:Assuming older ice is usually below the younger ice and the atmosphere is well mixed, then given any two ice sheets on earth, there should be a way compare them. The concentrations of different gases dissolved at different times should sequentially be the same. Like multi-colored stripes on a pole. The stripes may be different sizes, but they should be in the same order. If we can find the same sequences in gas concentrations across different ice sheets then we can start to put together a history of the Earth's atmosphere.Near the turn of the 21st century, geophysicists were working on exactly this problem. They were trying to calibrate the gas concentrations trapped in ancient ice samples by comparing ice from Antarctica with Greenland. And things just weren't adding up. The sequences didn't align. The gas concentrations were just too different. There was some kind of missing variable in the data.As it turned out, that variable involved cosmogenic muons.The Speed of Sound and LightTo understand how muons resolved this Paleoclimatology puzzle, we need to go back to the source. The source of cosmic rays.In episode two of this series we talked about Fermi Acceleration - the process by which electrically charged particles like protons get accelerated to outrageous velocities by SHOCKWAVES in astrophysical plasmas.And shockwaves occur in glacial ice too.To understand shockwaves, let's think about sound waves.Sound usually travels in the atmosphere like a wave. A wave of air pressure. Those atmospheric particles slam against each other in an organized and oscillating way, spreading out away from source.The speed of those waves depends on the amount and types of molecules present, as well as the overall temperature of the atmospheric gas. The sound waves we experience travel at around 343 meters per second, which is about 767 miles per hour.Here's the thing, humans routinely fly supersonic jets that travel faster than that.Supersonic jets - like fighter jets - travel faster than the speed of sound. They travel faster than noise they make. You can't hear them coming until they're already past you. And when you do finally hear them, it's a tremendous noise.It's a shockwave, actually, that you hear. The particles of air are being disturbed faster than speed of sound. In some sense, the sound waves that are produced all kind of pile up on each other, forming the shock front or wall of pressure that some folks call a sonic boom.It's a wall of energy collected by atmospheric particles moving far from equilibrium. This wall is similar to those plasma shockwaves that accelerated the cosmic rays deep in outer space.The important point is that the shockwave was generated by something moving faster than normal waves could. The jet was moving faster than speed of sound.As we'll now see, another kind of shockwave - one driven by cosmogenic muons - is responsible for disrupting the gases dissolved in that ancient ice.Quasi Particles of LightSo fighter jets move faster than the noise they make. That's a nice trick to try to sneak up on folks, but we have radar. Radar works by using radio waves - electromagnetic or light waves with really long wavelengths - and reflecting it off of objects. Unless the fighter jet is moving faster than the speed of light, we can still see it coming.But this whole idea presents a fun riddle. Question: When does the speed of light not equal the speed of light?Answer: When it is SLOWER than the speed of light.Wait. What?!Question: When is the speed of light SLOWER than the speed of light?Answer: When light moves through water. Or glass. Or. You guessed it. Ice.Wait. What?!Glass, like water, reflects and refracts light. You can typically tell when there's water in a glass, or when you're looking through a window. The light  coming through them behaves in a funny way. Things just look different. A straw inside your glass of water usually looks disconnected from the part of it that is outside.We usually say that water “bends” light. In physics class we say it refracts it. And this happens because light SLOWS DOWN A LOT when its inside water. Or glass. Or Ice. By a lot I mean like 30 percent.Microscopically, at the level of photons, of course that notion is silly. The speed of light is a constant. It's not LIGHT that's moving through the water, it's not a pure collection of photons per say. It's something else, something that connects with light, and it is light that comes out the other side.If that sounds a little wild, don't panic. It has a very simple physical analogy.Imagine being inside your home when a supersonic jet flies by. The shockwave of that sonic boom slams into your walls, shaking the windows and rattling your doors. Did the sound you hear come from molecules in the air? Sure. But the air inside your house. The molecules from the sonic boom slammed into your walls and windows, which in turn shook themselves. They vibrated in place. They vibrated in such a way that it shook the air molecules in your room, and the sound made it to your ears.Inside or outside, the sonic boom sounded basically the same. A bit muffled sure, but otherwise the same. Those sound waves from the air outside where transferred to the air inside through the physical materials of your house.Inside that glass of water, the electromagnetic energy is still moving. It's just tangled up now with all the electromagnetic fields of all the molecules moving around inside the fluid. The resulting excitations - the slower light waves if you like - aren't really made up of photons, they're collective excitations of an electromagnetic disturbance passing through. But once out the other side, they spit out photons again. The air of course also has an index of refraction so this is something of a simplification, but hopefully the point is clear. It's not pure photons that are traveling through the water, the glass or the ice. It's something else. And that something else - those quasiparticles - don't quite move as fast as light. They move a lot slower. 30 percent slower.Cherenkov RadiationCosmogenic muons travel at 99.4% of the speed of light. But light - or the quasiparticles that appear as light anyway - moves 30% slower in water or ice.So in water you cannot see those cosmogenic muons coming. Effectively, they're moving faster than the speed of light.  And that's trouble because they carry an electric charge.As you might recall from our earliest episodes, electrically charged particles transfer energy with each other by exchanging photons. Therefore, cosmogenic muons moving through an electromagnetically dense medium like glacial ice are creating distortions in that electromagnetic field faster than those distortions can propagate as waves.In short, cosmogenic muons create electromagnetic shockwaves in water, and glass and ice. Just like with the fighter jets whose sound waves all piled up into a sonic boom, the cosmogenic muons create electromagnetic disturbances in the ice that pile up to create a shockwave of light. Or you know, quasi-particle light inside the ice. Or water.Traditionally, those electromagnetic shockwaves are called CHERENKOV RADIATION.Cherenkov radiation is famous for the eerie blue glow it gives to the water inside of radioactive cooling ponds near nuclear reactors. It appears blue but the shockwaves are mostly in the ultraviolet or UV spectrum. UV photons - or their associated quasi particles - have a bit higher energy than visible light.And if there's one thing we know about ultraviolet light, it's powerful enough to burn our eyes and skin. That's because it's powerful enough to break down chemical bonds between organic molecules.Given that, can you guess what the different is between Greenland Ice and Antarctic Ice?The PaperOrganic Molecules. Frozen plant matter. Greenland's got it. Antarctica doesn't. Surrounded by water and much closer to life as we know it, Greenland ice has much more contaminants that the center of antactiac, which though covered in ice, is effectively a desert.In a 2003 paper published in Geophysics Research Letters, entitled “*In situ photolysis of deep ice core contaminants by Çerenkov radiation of cosmic origin*, the authors Augstin  Colussi and Michael Hoffmann argued that an unexplained excess of carbon monoixde gas trapped was consistent with the disintegration of the tiny bits of plant matter present in the Greenland ice by Cherenkov radiation induced by the flux cosmic rays.Remember, that's over a hundred cosmic rays per square meter per second!In 2007, those authors, together with Marcelo Guzman, now at university of Kentucky, published a follow on study describing concrete chemical mechanisms that could generate carbon monoxide and carbon dioxide from cosmic rays.While protected from the sun's natural ultraviolet rays by layers upon layers of ice, atmospheric gases from over a 1000 years go are still exposed to the penetrating flux of muons from cosmic rays. And the electromagnetic shockwave of those ridiculously fast muons - their Cherenkov radiation - constantly exposes organic matter to tiny bits of ultraviolet radiation. Just enough, as it turns out, to rip a few carbon atoms off of some big, frozen organic molecules to mix with the otherwise trapped, historical atmospheric gas.Like adventure, elementary particles are everywhere, my friends. Go seek them out.

The team pretends to run around in a giant pyramid. Muons, neutrinos, and sparkles fly around all over the place. Daniel learns that, like a solar eclipse, you should never directly at a crystal skull. And we find out that Daniel and his grandfather are pretty much the exact same person.

All the time.On average, every square centimeter of Earth sees a muon about once a minute.  While that might not seem like a lot, if you consider your personal space. Say, about square meter around you - you know, 10 square feet . Over 160 muons pass through your personal space per second! Per second!Those muons coming form the upper atmosphere. They are the debris left over from the constant bombardment Earth experiences from high energy cosmic rays.If only there was a way to see them.Do you remember when I said that a particle physicist will look for particles WHEREVER they can find them? Well, before weather balloons, before particle colliders, there were cloud chambers.Cloud chambers are boxes full of super saturated vapor or some kind. Any little disturbance will cause that vapor to condense, as clouds do up in the sky.High energy particles blasting through a cloud chamber leave tracks. Little clouds form around the path of the particle, just like the contrails of a jet flying through the sky.The muon and the positron were both discovered this way!Cloud chambers are fun because you can build them yourself at home! The main thing you need is a sustained temperature gradient and tiny bit of very pure isopropol alcohol.We'll link to two great examples of DIY cloud chamber designs in the show notes.Building a cloud chamber at home is a great way to come face to face with the fact muons - the debris from cosmic rays - are passing through us all the time.The Atmosphere as a Muon FilterThe magnetic field generated by the Earth's core protects us from many incident particles from space. Especially all that plasma in the solar wind.But those high energy cosmic rays blast straight through the magnetic field. It's just not strong enough to contain them.Our upper atmosphere is our next layer of defense. Cosmic rays collide with its molecules tens of miles above the Earth, creating a shower of debris that itself can be miles across. In some sense, the atmosphere serves as a filter, converting all those particles like protons and pions into muons. Muons comprise the bulk of what we see down here at the surface. Muons are unstable particles. They decay to electrons after about 2.2 microseconds. This means that while many muons make to the ground, not all of them do. The higher you are above sea level, the more muons you're likely to see.At 10,000 ft above sea level, this number can triple! Given that commercial airline flights typically occur above 40,000 ft, it's important to realize that flying exposes you to more Cosmogenic Muons.Fortunately for you frequent flyers, the extra does radiation exposure is still a very small amount of radiation exposure! The International Commission on Radiological Protection has well established professional limits to protect even commercial flight crews from exposure to all those cosmogenic muons.Long Lived MuonsDespite the atmospheric filter, those Cosmogenic Muons are still traveling really, really fast. Like 99.9 percent of the speed of light fast. Muons moving that fast don't behave like you'd expect. For one thing, they take far longer than they should to decay.How do we know that?As you might recall from their eponymous episode, muons only live for about 2.2 microseconds. That's 2.2 millonths of a second. Even traveling near the speed of light, that's simply not enough time to get from the upper atmosphere to anywhere near the surface of the Earth. That's a bit over 9 miles - or 15 kilometers. It takes light about 50 microseconds to travel that far.Muons that make it to Earth, then, live over 22 times as long as they should.Why that happens - what causes the muons to live so long - requires a small digression on the theory of relativity. On Special RelativityAs they say, Nothing travels faster than the speed of light. Which is true, at least, in outer space and to some extent in the air around us. You see, it's not so much that LIGHT is the fastest thing around. It's that the universe itself has a maximum possible speed - a speed limit, if you like - which is just shy of 300 million meters per second.When left to its own devices, light - or any particle with zero mass - travels at that speed.That universal speed limit is just a fact of life, but we don't notice is much because a typical human moves at about 1 meter per second. Not 300 million meters per second.But having a speed limit like the speed of light leads to some pretty strange paradoxes.For example: you cannot race a photon. Photons, you might recall, are particles of light.If you ran towards a photon, the photon sill still move away from you at the speed of light.If you drove towards the photon at 100 miles and hour, the photon will still move away from you at the speed of light.If you jumped into a supersonic fighter just and chased a photon, the photon will still move away from you at the speed of light.Even if you built and launched in a rocket ship so fast you were traveling at 200 million meters per second - you know, 67% of the speed of light - and chased that photon, the photon will still move away from you at the speed of light.At least in the vacuum of space, light always moves at the speed of light. No matter how fast you are going. Frustrating, huh? Maddening even. But that's how the universe enforces its speed limit. No matter how hard you try, you can never catch up.But how could this be? What weirdness could explain this paradox?Well speeds don't really add like normal numbers do. This is Einstein's famous theory of Special Relativity. There's re some technical details and nuances of course, but essentially, relativity says that light always moves at the speed of light, relative to you.The implication is that EVERYONE, ANYONE sees light moving at the same speed, no matter how fast they're moving.That same universal speed limit, just shy of 300 million meters per second.The way the universe affords this is by exchanging your perception of time for a perception of distance.The faster you go, the LONGER the distance you have to travel. Your perception of one meter is LONGER than someone going slower than you. That's why is so hard to get up to light speed. The faster you go, the further you have to go to catch up. Of course, to account for this cheat, the universe also shortens your sense of time. So yeah you have to go further, but you don't really notice that because time has slowed down for you. But the net result is even “doubling your speed” only really inches you closer to the speed of light.In a VERY real sense, motion trades TIME for SPACE. At least that's how the mathematics of special relativity work out. In some sense, trading time for space is literally what it means to be in motion.If that's too heavy to take in, don't worry about it. If it excites you, AWESOME. I'll link to some further reading on special relativity in the show notes. But in either case, all you need to know at this point is that those cosmogenic muons, those particles screaming in at over 99% of the speed of light, have traded a LOT of their sense of time for space. So their internal clocks ticks much, much, much slower. Well over twenty times slower! Which is why they take so long to decay.In other words, the cosmogenic muons all around us near the surface of the earth - the things you can detect with your own cloud chamber at home - are a testament to the peculiarity of Einstein's theory of special relativity.ConclusionMuons, borne of debris from cosmic rays collisions in the upper atmosphere, travel at outrageous speeds to surround us here on the surface of the Earth. They travel so fast that Einstein's theory of special relativity directly manifests itself in the very existence of those muons.Other particles created in those cosmic rays collisions - like pions or lambda baryons - are also moving at outrageous speeds, but since they contain quarks, they communicate via all of nature's forces. They are much more susceptible to not only decay but collisions with other particles. Far more susceptible than the muons are.Even the humble electron, when traveling at relativistic speeds, will quickly lose much of its energy via the brehmstrahlung radiation, which depends inversely on its small mass. Muons, being heavy, don't have this problem. So this is what we mean when we say the atmosphere behaves like an energy filter, catching all that cosmic ray collision energy, all except for those muons. They're fast, heavy and don't interact as frequently.But they do eventually interact. With the molecules in our body. In the rocks. Or even, in the snow and ice the covers the high mountain tops and polar regions of our Earth. In our concluding episode in this mini-series, we'll explore how cosmogenic muons have helped scientists understand the history of Earth's atmosphere and the associated implications for its climate.

“Her Favourite Hitchcock Films” A native of Northern California, Jerry Vessel was the bassist for the beloved San Francisco outfit Red House Painters. The band, who formed in 1989, put out four albums on 4AD and toured all over North America and Europe before calling it a day in 2001. Post-Painters, Vessel played drums for the Muons and bass for Six Eye Columbia and he also put out two solo albums under the moniker Heirlooms of August. Heirlooms' sophomore album Down at the 5-Star found one of the songs featured in the TV series Parenthood. Vessel's third effort is under his own name this time around and it really makes sense. A stripped down affair that's stark, spare, personal and unflinchingly honest, Her Favorite Hitchcock Films was written about his relationship with fashion designer Alexis O'Connell and it not only details their time together, it also confronts dealing with her sudden loss. Punctuated by piano violins, cellos, and atmospheric production courtesy of American Music Club's Bruce Kaphan, the compositions on Her Favorite Hitchcock Films are as poetic as they are conversational. Beautifully constructed, they're parenthetical, interstitial, referential and emotional. Name-checking Darby Crash, David Lynch, aluminum boats, Thelonious Monk, druid forts and Townes Van Zandt, the songs that make up this album are filled with lyrical intensity in that they conjure the world Vessel and O'Connell built and occupied together. When you're close with someone you construct universes that are made up of the things you mutually love and this is a stirring homage to those universes. Yes, there's darkness and of course, there's pain here, but every song is charged with love. It's vulnerable but in that vulnerability there's tremendous life-affirming strength. It's quite an album. And this is quite a conversation—Vessel talks to Alex about grief, his friendships with his former Red House Painters bandmates, Townes Van Zandt, Lynyrd Skynyrd, Jack London and why the piano was his go-to instrument this time around. www.jerryvesselmusic.bandcamp.com www.jerryvesselmusic.com www.bombshell radio.com www.alexgreenonline.com

Get in touch.The TauThe tau is a very heavy species of elementary particle that aren't quite as common as the electron or the muon. Nevertheless, just as the muon shares many of the properties with the electron, so too does the tau.Like all elementary particles, taus have no known size. But they do have a known mass. At 1776.86 MeV, it's a pretty big mass. That's well over 3000 times the mass of the electron, or just shy of 17 times the mass of the muon. That large mass is key to understanding the tau, especially how it decays.Taus are not stable. Heavy particles rarely are. Taus decay to all kinds of other stuff. Generally, heavier particles can decay into lighter particles so long as things like electric charge are conserved. Muons aren't terribly heavy, and so decay primarily to electrons because there's not much else to decay to. Taus by contrast, are so heavy they can decay into all kinds of things.Because taus are so heavy, they can decay to hadrons - a fancy name for all that nuclear junk - and those decays happen quickly. Very quickly. There are just so many options. On average the taus only live for about 2.9×10^-13 seconds. Forget nanoseconds. That's less than a picosecond! That's why taus so rare, they just don't survive very long.Taus, like electrons, also have antiparticle partners. The antitau, which comes complete with a positive electric charge.Eighty-six percent of the time, taus decay to nuclear junk. There are so many possibilities. The other twenty-four percent of tau decays go to muons. Given the large mass of the tau, there is a lot of rest mass energy - E = mc^2- to go around. Cataloging all the different options is a precision science that lets us study the minute details of particle physics. Those details can tell us a lot about other kinds of things. The tau is the heaviest in the family of charged leptons: Electron. Muon. Tau. So far as we can tell, that's the end of the pattern. Calculations have shown that another, even heavier version of the electron would throw off many of the precise relationships between other particles, and lead to predictions that are already ruled out by experimental observations.Like I said, those precision details of tau decays - together with other precision measurements in particle physics - can tell us a lot about our universe.

Get in touch.The MuonMuons are a lesser known species of elementary particles that are extremely common, at least on Earth. They're falling all around us, all the time. Muons are created by the collision of particles from outer space smashing into the molecules of the upper atmosphere.Like all elementary particles, muons have no known size. But they do have a known mass. At 105.7 MeV, its a moderately sized mass. Its about two hundred times the mass of the electron. The muon's electric charge is identical with that of the electron. Indeed, the muon and the electron share many of the same properties.Like the electron, the muon interacts via the electromagnetic, weak and gravitational forces.Unlike the electron, muons are not stable particles. Heavy particles seldom are. They're heavy, and because they otherwise act like electrons, they decay to electrons. That's a pattern we will see in particle physics, over and over again.Muons also have antiparticle partners. Like the positron they're also positively charged. Since muons and antimuons decay, we don't usually worry too much about who's who, unless we're counting charges.Muons decay courtesy of the weak nuclear force, which of course, is a very weak force. So that decay takes a long time. Muons, despite being unstable, are relatively long lived particles, hanging around just over a couple of microseconds. By particle physics standards, a microsecond is an eternity.Muons typically decay into electrons and a pair of neutrini: very light, electrically neutral particles we will meet soon. That decay process is mediated by a heavy, photon like particle, the W boson.Schematically, the muon transforms into that W-boson and a muon neutrino. The W-boson itself then transforms into the electron and an anti-electron neutrino.Life is complicated, of course, and there are a few other alternative scenarios. You see, E=mc^2, and the mass difference between the muon and an electron is pretty sizable, so much of that extra energy gets converted into velocity. But conservation of energy still allows for a few other options.Occasionally - far less than one percent of the time - the muon's decay will create a bonus pair of particles: an electron/positron pair. Rarer still, an extra photon will be produced. Muons, electrons and the W-bosons all participate in the electromagnetic force, so while rare, it isn't totally unexpected.You might be surprised to learn that muons make up a pretty sizable chunk of your annual exposure to radiation. Especially if you fly.

Something is up with muons. They are not behaving in the way we would expect. Does this mean our model of the universe is wrong? Lily explains to her Dad what is going on, why the Standard Model is always evolving, and just what on earth the Standard Model is anyway. She is helped by Dominika Vasilkova, a PhD student at University College London who works on Fermilab's g-2 experiment - the actual experiment which is bringing the strange behaviour of muons to light.

When subatomic particles make news, Dr Karl and Professor Lewis are ready to help. The "chubby electron" has been neglected for decades, so why the fuss ? By popular request here is a special episode dedicated to why muons matter. www.geraintflewis.com http://drkarl.com  

Dr. Weiping Yu returns to the show with a brand new segment of Science and U. The physicist comments on the muon results that show discrepancies in the standard theory of fundamental particles. "I believe there are no orbiting electrons," Dr. Yu astonishingly claims. Dr. Yu also comments on the news that MOXIE has produced five grams of oxygen on Mars.

They get all science again talking about the problems with muons. Recent discoveries are fun. They smoke another Room 101. The  Ichiban Maduro Toro. They drink Gautier VS Cognac. How to kill flies. Florida strikes down a bill that would ban smoking on beaches and parks.

Andrea Macdonald founder of ideaXme interviews Dr. Kevin Pitts, Chief Research Officer at Fermilab and Physics Professor, University of Illinois. They spoke of 2 exciting research projects. The first focuses on neutrinos and the second on muons: Will these experiments reveal new laws? 13.8 billion years ago matter pitted against antimatter and won. DUNE, a new experiment in the making, hosted by Fermilab attempts to discover why matter won - that is, why the universe and galaxies exist at all. The current models dictate that the Big Bang created equal parts matter and antimatter. Within a second, all the matter and antimatter should have met and annihilated, leaving behind a universe with nothing but energy in the form of light. The first results for a second experiment from the same lab - Muon g-2 were recently published. Although, at the early stages of the experiment (5 runs in total and less than 10% of the data processed) many believe that the results to date show promise to challenge The Standard Model of Physics. Dr. Kevin Pitts: Kevin Pitts of the University of Illinois has been named chief research officer at Fermilab National Accelerator Laboratory beginning March 1. His focus will be on oversight for the international Deep Underground Neutrino Experiment, including advancing scientific excellence across the laboratory through strong communication, collaboration and coordination with the Department of Energy and other partners. He joins the laboratory as it prepares to usher in a new era of science and innovation in particle physics research and discovery. “We are proud to have Kevin Pitts join Fermilab at a time when DUNE is underway,” said Joe Lykken, deputy director for research at Fermilab. “His leadership and research collaboration with Fermilab make him the ideal person to direct the development of the DUNE research program both at the laboratory and with our partner institutions.” Upon its completion, DUNE, supported by the Long-Baseline Neutrino Facility, will make Fermilab the premier neutrino research institution globally. DUNE is the first international mega-science project at a DOE lab and Fermilab’s flagship project. Hosted by Fermilab, it comprises over 200 institutions in more than 30 countries. Construction work for LBNF, along with the PIP-II accelerator, are in progress at Fermilab in Illinois and at the Sanford Underground Research Facility in South Dakota. Pitts joins Fermilab after 22 years with the University of Illinois where he was most recently the vice provost for undergraduate education and a professor of physics in the Grainger College of Engineering. He has a long history working on experiments at Fermilab, including participation in the discovery of the top quark in 1995. Additionally, he has been serving on the Long Baseline Neutrino Committee since 2016. “Fermilab has been an important part of the first-half of my career and I am thrilled to be joining the laboratory as chief research officer,” Pitts said. “After numerous Fermilab research projects and collaborations, I am honored to be leading the ball down the field to further the development of DUNE and other neutrino research projects.” He received a B.A. in physics and mathematics from Anderson University and M.S. and Ph.D. degrees in physics from the University of Oregon. Pitts was a research associate at Fermilab on the CDF experiment. He also works on the Muon g-2 experiment. Kevin Pitts is a fellow of the American Physics Society, the American Association for the Advancement of Science, and is a member of the Particle Physics Project Prioritization Panel. He has received numerous awards and recognitions for his research, teaching and advising. Fermilab is supported by the Department of Energy Office of Science. The DOE Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.

From Insects to Muons Engaging the Sciences at Trinity School

On apprenait récemment une découverte qui pourrait transformer le monde de la physique si elle s’avère confirmée. Avec un accélérateur de particules, des scientifiques de la communauté internationale ont observé que les particules élémentaires, les muons, pouvaient réagir à un champ magnétique d’une façon jamais observée auparavant. Si elle est confirmée, cette découverte d'un nouveau type de force naturelle aura un impact majeur sur notre compréhension de l'univers.  Avec Félix Pedneault et Charles Trahan  Une production QUB radio Avril 2021 Pour de l’information concernant l’utilisation de vos données personnelles - https://omnystudio.com/policies/listener/fr

Fermilab released the first results of their Muon g-2 experiment this week, and the fundamental particles don’t behave as predicted by the Standard Model of particle physics. Plus, dust, more dust, Martian water (again), and a review of Packing for Mars by Mary Roach.

On Wednesday the EU’s EMA and UK’s JCVI announced a suspected correlation between vaccination and an extremely rare type of blood clot. Prof Sabine Eichinger is a co-author of a new paper suggesting a link with vaccination or the immune response to Covid vaccination and suggests the name VIPIT for the condition. One of her patients died at the end of February having presented with a rare combination of symptoms – blood clots and a low blood platelet count. Sabine tells Roland the dots they have managed to join in the story so far. Scientists at Fermilab in the USA posted four papers and announced an exciting development in particle physics that might lift the curtain on science beyond the Standard Model. Their measurement of something known as g-2 (“gee minus two”, just fyi), by measuring with phenomenal accuracy the magnetic properties of muons flying round in circles confirms a 20-year old attempt at a similar value by colleagues at Brookhaven. At the time, it was breathtaking but suspicious. Muons, rather like heavy electrons, don’t quite behave as the Standard Model might have us believe, hinting at fields and possibly particles or forces hitherto unknown. Dr. Harry Cliffe – a member of the LHCb team who found something similarly weird two weeks ago - describes the finding and the level of excitement amongst theorists worldwide. Superfans around the world have learned to speak fluent Klingon, a fictional language originating from Star Trek. In a quest to understand the science behind these languages often dismissed as gobbledygook, Gaia Vince has been speaking to some of the linguists responsible for creating these languages. It’s time for her to relax the tongue, loosen those jaw muscles and wrap her head around the scientific building blocks embedded in language and what languages like Klingon tell us about prehistoric forms of communication. Also, gossip often has negative connotations, but does get a bad rap? Might it serve a useful function and should we think of gossiping as an advanced social skill rather than a personality defect? CrowdScience listener Jayogi thinks it might be useful, and has asked CrowdScience to dig into the reasons why we find it so hard to resist salacious stories. Datshiane Navanayagam meets a scientist who views gossip as a key evolutionary adaption - as humans started to live in bigger cooperative groups, gossiping was a way of bonding and establishing acceptable group behaviour as well as cementing reputations of trustworthiness. Datshiane heads to the local park to catch some real gossiping in action and finds out that whilst people like to gossip they don’t consider themselves gossipers. Datshi asks a team of scientists what information we are most keen to share and glean in these interactions and if there is such a thing as ‘good’ and ‘bad’ gossip. She hears that in some group settings – like in the workplace - gossip can enhance cooperation and limit free-riders, but that it can also have a more self-serving dark side. Datshiane finds out if our stone-age gossipy minds are fit to operate in the world of mass communication and social media – is our fixation on celebrities related to our being hard wired to gossip?

On this episode of Fault Lines, hosts Jamarl Thomas and Shane Stranahan talked about PBS whitewashing a former Al Qaeda leader, a new test on muons set to reshape modern physics, the latest on the USPS, the Amazon unionization vote in Alabama, and Biden's new personnel pick to stop Nord Stream 2. Guests:Maram Susli – Political Commentator and Geopolitical Analyst | PBS's Frontlines Whitewashing of Former Al Qaeda LeaderMarkus Klute – Professor of Physics | New Fermilab Muon Test Will Force a Deeper Rethinking of Modern PhysicsChuck Zlatkin – Legislative and Political Director for New York Metro Area Postal Union | The USPS's Ten Year Plan and the DEJOY ActProf. John Logan – Professor and Director of Labor and Employment Studies at SFSU | Amazon Unionization Vote: Looks Like A No, Potential Union Busting TacticsPeter Oliver – EU correspondent for RT International | Amos Hochstein: Biden's Pick to Stop Nord Stream 2In our first hour we were joined by Maram Susli to talk about an article and upcoming documentary on Abu Mohammad al-Jolani, the former head of Al Qaeda in Syria who rebranded as the head of Hayat Tahrir al-Sham, a force fighting the Syrian government alongside U.S. Islamist proxies. We turned to Antony Blinken's morally blind comments on saving children in Syria and surveyed the strategic and economic importance of the Golan Heights.In our second hour we were joined by Markus Klute to talk about a new test out of Fermilab that confirms a 20-year-old discovery shaking up modern physics from its foundations. We talked about muons and Higgs bosons, asking why this new discovery is so significant and what questions it may pose for quantum physicists and mathematicians looking to understand our universe on its deepest known levels..Later in the hour we were joined by Chuck Zlatkin to review the legacy of Louis DeJoy, Postmaster General for the United States Postal Service, talking about attempts to private the USPS, the slowdowns to be implemented in the USPS's new 10-year plan, and the DEJOY Act and what it would entail.In our last hour we were joined by John Logan to talk about the ongoing count of the Amazon unionization vote in Bessemer, Alabama, which at a 2-to-1 margin now looks to be set to shut down the prospect of the plant forming a union. Later in the hour we were joined by Peter Oliver to talk about Amos Hochstein, Biden's new pick for special envoy on Nord Stream 2, and how his history as a member of a supervisory board for a Ukrainian gas company leaves him ill-fit to head the United States' response to Nord Stream 2.

By which we mean: not aliens. 00:15:08 Lentils might not sound like exciting archaeological discovery, but a find at the prehistoric site of Gurga Chiya in Iraqi Kurdistan could provide clues about the formation of permanent settlements and the development of social stratification. 00:22:45 Using muon-scanning technology, particle physicists have discovered a hidden void inside the Great Pyramid of Giza. But - surprise! - that's not as unusual or revolutionary as much of the media breathlessly reported.   This episode contains traces of archaeologist Zahi Hawass criticising the Great Pyramid void discovery on RT America.

Today we tackle some Cosmic Quantum Physics - Muon energy particles. muons are an unstable subatomic particle of the same class as an electron (a lepton), but with a mass around 200 times greater. Muons make up much of the cosmic radiation reaching the earth's surface. Learn what is Cosmic Energy, the History of its discovery and measurement and methods to use it in the Vastu.

Muons are very small fundamental particles that are much heavier than they should be.  they fall apart pretty quickly, but they rain down on us. It's magical. Today's physicists are Ryan Martin, the particle physicist; and Diana Cowern, host of the "Physics Girl" youtube channel.   Our Guest this time is Sarah Gailey, the author!

La collaboration Pierre Auger, qui étudie les rayons cosmiques ultra-énergétiques via les gerbes de particules qu'ils produisent dans l'atmosphère, vient de trouver que ces particules produisent plus de muons que ce que prédisent les modèles théoriques utilisés au LHC, une anomalie encore inexpliquée.

The lecture begins with the development of post-Newtonian approximations from Newtonian terms. Several problems are worked out in calculating mass, force and energy. A discussion follows about how concepts like mass and velocity are approached differently in Newtonian physics and Relativity. Attention then turns to the discovery that space and time change near the speed of light, and how this realization affected Einstein's theories. Finally, the possibility of traveling faster than the speed of light is addressed, including how physicists might predict from laboratory conditions how this might occur. Muons, unstable particles that form at the top of the Earth’s atmosphere, are used as an example.

One of the physics goals of the COMPASS experiment at CERN was to measure the contribution of gluons to the nucleon spin. To achieve this, it was proposed to scatter polarized Value{160}{GeV/c} muons on a polarized deuteron target and to detect $D$ mesons in the final state. The underlying process in this $D$ meson production is supposed to be the Gls{PGF}, where a virtual photon emitted by the muon interacts with a gluon from the target nucleon, producing a charm-anticharm quark pair. Fragmentation of a charm (anticharm) quark leads with high probability to the creation of a $DZ$ or $D^*$ meson, which COMPASS detects via the $D^0 to Kpi$ and $D^{*} to D^0 pi to Kpipi$ decay modes. From the longitudinal cross section spin asymmetries of the $D$ meson production and theoretical predictions for the Gls{PGF} cross section, the gluon contribution to the nucleon spin has been measured by the COMPASS experiment. The results presented in the thesis are the following. Based on data from the year 2004 a total visible cross section of TotalCrossSection, for the $D^*$ meson production, has been measured, with the error being dominated by systematic effects. It is validated that the $D$ mesons are indeed produced through the Gls{PGF} process, by comparison of measured $D$ meson kinematic distributions to the ones predicted by a theory (AROMA generator). A good agreement was found for the distribution shapes, which confirms that Gls{PGF} plays a major role. However, a $20%$ difference was found in the number of produced $DZ$ and $aDZ$ mesons (and for the $D^{*+}$ and $D^{*-}$ mesons as well) which is significantly larger than predicted by AROMA. Kinematic distributions of $D^0$ and $D^*$ mesons were compared with the background and also with the nearby $KTS$ resonance, using all longitudinal data taken in 2002-2006. The particle-antiparticle asymmetry has been studied as a function of several kinematic variables. The $20%$ excess of mesons decaying into $K^+pi^-$ over mesons decaying into $K^-pi^+$ was observed for all three mesons. The behavior of the $DZ/aDZ$ (and $D^{*+}/D^{*-}$) asymmetries as a function of virtual photon energy suggests that associated production of $D^{*-}Lambda_c^+$ or $overline{D^0}Lambda_c^+$ may be responsible for the observed effect. The longitudinal double spin asymmetries have been studied for the $D^0$, $D^*$ and $KTS$ mesons separately for particle, antiparticle and for the sum of particle and antiparticle. It was found that the asymmetries extracted for $D^0$ and $D^*$ mesons are compatible with zero. A 3-sigma deviation from zero asymmetry was observed for the $KTS$ meson. An investigation of the $KTS$ double spin asymmetry reveals a dependence as function of the Bjorken $x_{Bj}$ variable.
