The Relativistic Heavy Ion Collider (RHIC), the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set of instruments based at New York's Brookhaven National Laboratory, and was designed to accelerate gold ions to near-light speed before collision. It was the second most powerful accelerator on the planet, second only to CERN's Large Hadron Collider. Since RHIC began running in 2000, scientists have used it to study the tiniest subatomic particles, which give insight into some of the universe's biggest questions. Brookhaven nuclear physicist Gene Van Buren joins Host Flora Lichtman to look back on the history of RHIC, what physicists have learned from the collider, and what lies ahead for particle physics.Guest: Dr. Gene Van Buren is a nuclear physicist at Brookhaven National Laboratory in Upton, New York.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

I am an experimentalist working the field of nuclear and particle physics. I am a SUNY Distinguished Professor at Stony Brook University. I also serve as the Electron Ion Collier (EIC) Science Director at BNL and Director of the Center for Frontiers in Nuclear Science (CFNS). I like to use “spin” as a tool to investigate and understand nature — thus I always use polarized beams or targets. I have been involved experiments at BNL (both RHIC and AGS), at Jefferson Lab, PSI, CERN and DESY. These experiments addressed my interests in nucleon spin structure and also precision electroweak physics that push the boundaries of the Standard Model of Physics. In every one of them the property of “spin” played an important or pivotal role. I was one of the earliest Electron Ion Collider (EIC) enthusiast, having been involved from its birth/infancy to now- when it is being realized. It has been a privilege to be involved or participating in the US long range planing process since 2001 in all things related to the EIC. Through those years I learnt so many other things from friends and colleagues in our field including the wonderful initiatives like the FRIB which is operational now and the neutrino-less double beta decay experiments - which hopefully will also happen soon. My Journey as a Physicist is brought to you by PhD student ⁠Bryan Stanley⁠ (he/him/his) and Prof. ⁠Huey-Wen Lin⁠ (she/her). Season 3 is hosted by PhD student Bill Good and edited by Kiran Sakorikar.

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is Highly Advanced Epistemology 101 for Beginners, Part 15: Mixed Reference: The Great Reductionist Project, published by Eliezer Yudkowsky. Followup to: Logical Pinpointing, Causal Reference Take the universe and grind it down to the finest powder and sieve it through the finest sieve and then show me one atom of justice, one molecule of mercy. - Death, in Hogfather by Terry Pratchett Meditation: So far we've talked about two kinds of meaningfulness and two ways that sentences can refer; a way of comparing to physical things found by following pinned-down causal links, and logical validity by comparison to models pinned-down by axioms. Is there anything else that can be meaningfully talked about? Where would you find justice, or mercy? Suppose that I pointed at a couple of piles of apples on a table, a pile of two apples and a pile of three apples. And lo, I said: "If we took the number of apples in each pile, and multiplied those numbers together, we'd get six." Nowhere in the physical universe is that 'six' written - there's nowhere in the laws of physics where you'll find a floating six. Even on the table itself there's only five apples, and apples aren't fundamental. Or to put it another way: Take the apples and grind them down to the finest powder and sieve them through the finest sieve and then show me one atom of sixness, one molecule of multiplication. Nor can the statement be true as a matter of pure math, comparing to some Platonic six within a mathematical model, because we could physically take one apple off the table and make the statement false, and you can't do that with math. This question doesn't feel like it should be very hard. And indeed the answer is not very difficult, but it is worth spelling out; because cases like "justice" or "mercy" will turn out to proceed in a similar fashion. Navigating to the six requires a mixture of physical and logical reference. This case begins with a physical reference, when we navigate to the physical apples on the table by talking about the cause of our apple-seeing experiences: Next we have to call the stuff on the table 'apples'. But how, oh how can we do this, when grinding the universe and running it through a sieve will reveal not a single particle of appleness? This part was covered at some length in the Reductionism sequence. Standard physics uses the same fundamental theory to describe the flight of a Boeing 747 airplane, and collisions in the Relativistic Heavy Ion Collider. Nuclei and airplanes alike, according to our understanding, are obeying special relativity, quantum mechanics, and chromodynamics. We also use entirely different models to understand the aerodynamics of a 747 and a collision between gold nuclei in the RHIC. A computer modeling the aerodynamics of a 747 may not contain a single token, a single bit of RAM, that represents a quark. (Or a quantum field, really; but you get the idea.) So is the 747 made of something other than quarks? And is the statement "this 747 has wings" meaningless or false? No, we're just modeling the 747 with representational elements that do not have a one-to-one correspondence with individual quarks. Similarly with apples. To compare a mental image of high-level apple-objects to physical reality, for it to be true under a correspondence theory of truth, doesn't require that apples be fundamental in physical law. A single discrete element of fundamental physics is not the only thing that a statement can ever be compared-to. We just need truth conditions that categorize the low-level states of the universe, so that different low-level physical states are inside or outside the mental image of "some apples on the table" or alternatively "a kitten on the table". Now we can draw a correspondence from our image of discrete high-level apple objects, to reality. Next we ne...

In collisions of ultra-intense laser-pulse with relativistic electrons as well as in ultra relativistic heavy ion collisions at RHIC and at LHC it is possible to probe critical acceleration a=mc^3/hbar. The behavior of a particle undergoing critical acceleration challenges the limits of the current understanding of basic interactions: little is known about this physics frontier; both classical and quantum physics will need further development in order to be able to address this newly accessible area of physics. The problem of critical acceleration is closely connected to strong field particle production, Mach's Principle, Unruh and Hawking radiation.

Can you imagine how the matter behaved right after the Big Bang? Consider two atomic nuclei flying toward each other with almost speed of light. What happens if they collide? We create a tiny unstable droplet of the primordial matter. This matter has nothing in common with the ordinary matter which surrounds us. It is much denser and extremely hot (temperature > 1 000 000 000 000 000 C). The field researching that is called the heavy ion collisions physics, and the matter is called quark-gluon plasma. This is the second and the last pilot episode of the Born to science podcast and today’s guest is a professor Boris Tomasik. He develops the theory of heavy ion collisions in the Czech Technical University in Prague and the Matej Bel University in Slovakia. We will discuss what quark-gluon plasma is, how we create it and how it behaves. Enjoy! This episode was supported by the COST-THOR EU programme. p.s. This is the last pilot episode of the podcast.

Destruir la tierra es más difícil de lo que alguna vez hayas podido imaginar. Hemos visto películas de acción donde el malo amenaza con destruir la tierra. Hemos oído a gente en las noticias afirmar que la próxima guerra nuclear amenaza con poner fin a este mundo. Tonterías. La Tierra es una gran bola de hierro de 5,973,600,000,000,000,000,000 toneladas. No es tan fácil de destruir. Declaración de misión. Primeramente, habría que definir la destrucción de la Tierra de tal forma que ésta no pudiese ser considerada como un planeta. Las posibilidades serían la división en dos o más planetas, en un gran número de pequeños asteroides o en una nube de polvo. Para elaborar la lista se han tomado sólo aquellas opciones que, de acuerdo con la ciencia, son posibles, si bien pueden ser muy poco probables. Los métodos están ordenados según su viabilidad, me menor a mayor. De esta forma, el nº 10 es el menos probable de darse, mientras que el nº 1 sería el más fácil de darse. Actual estado de destrucción de la Tierra. Número de veces que ha sido destruida la Tierra: 0 Número de planes actualmente en progreso con el objetivo de destruir la Tierra: 0 Número de experimentos científicos en proceso que podrían traer la destrucción de la Tierra: 0 Menor tiempo hasta que la Tierra sea destruida por medios naturales: 25 años Menor tiempo hasta que la Tierra sea destruida por medios artificiales: 50 años Lo que no es esta guía. Esta guía no es para aquellos cuyo objetivo sea exterminar a la humanidad. No se puede garantizar la completa extinción de la raza humana por estos métodos. La humanidad es astuta y tiene recursos, y muchos de estos métodos tardarían muchos años en hacerse realidad. Para entonces quizás nos hayamos extendido a otros planetas o incluso a otros sistemas estelares. Si tu objetivo es el genocidio humano completo, estás leyendo el documento incorrecto. Hay formas mucho más eficientes de hacer ésto, muchas de las cuales están disponibles y son viables actualmente. Tampoco es una guía para los que quieren aniquilar la vida de toda célula, hacer a Tierra inhabitable o simplemente conquistarla. Éstas serían metas mucho más fáciles en comparación. Ésta es una guía para aquellos que quieren que la Tierra deje de existir. Top 10 10. Fallo total de la existencia Necesitas: Nada Método: No hay método. Simplemente siéntate y espera a que los 200,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 átomos que componen la Tierra dejen de existir espontáneamente y al mismo tiempo. 9. Engullida por materia extraña. Necesitas: Materia extraña estable Método: Secuestrar el Relativistic Heavy Ion Collider del Brookhaven National Laboratory, Long Island, New York. Usa el RHIC para crear y mantener materia extraña. Mantenla estable hasta que absorba toda la Tierra en una masa de quarks extraños. Mantener la materia extraña estable es una tarea increíblemente difícil una vez absorbida, pero puede haber soluciones creativas para conseguirlo. Lo que queda de la Tierra: una enorme masa de materia extraña. 8. Absorbida por un agujero negro microscópico. Necesitas: Un agujero negro microscópico. Ten en cuenta que los agujeros negros no son eternos, sino que desaparecen al tiempo debido a la radiación Hawking. Para un agujero negro medio este tiempo es enorme, pero para uno muy pequeño podría ocurrir casi instantáneamente, ya que su tiempo de vida depende de su masa. Además el agujero negro microscópico debería tener más masa que el monte Everest. Método: simplemente coloca el agujero negro en la superficie de la Tierra y espera. Los agujeros negros tienen una densidad tan grande que pasan a través de la materia como una piedra a través del aire. El agujero negro caerá en picado hacia el centro de la Tierra hasta llegar al otro lado, devorando en su camino materia. Al llegar al otro lado, volverá y así oscilará una y otra vez como un péndulo que absorbe materia. Finalmente, habrá absorbido suficiente materia para disminuir su velocidad. Sólo necesitas esperar mientras consume materia hasta que toda la Tierra haya desaparecido. Muy, muy poco probable. Pero no imposible. Lo que queda de la Tierra: una singularidad de un tamaño casi cero que comenzará a orbitar alrededor del Sol. 7. Explosión por una reacción materia-antimateria. Necesitas: 2.500.000.000.000 toneladas de antimateria. La antimateria es la sustancia más explosiva. Puede ser fabricada en pequeñas cantidades usando un gran acelerador de partículas, pero producir las cantidades necesarias llevaría mucho tiempo. Si puedes crear las maquinaria necesaria, podría ser posible -y mucho más fácil- simplemente llevar 2.5 trillones de toneladas de materia a una cuarta dimensión, convirtiéndola en antimateria toda de una vez. Método: Este método implica detonar una bomba tan grande que haga explotar la Tierra en pedazos. ¿Cuánto de complicado es ésto? La energía gravitatoria vinculada a la masa de un planeta de masa M y radio R está dada por la fórmula E=(3/5)GM^2/R. Para la Tierra, ésta es aproximadamente de 224.000.000.000.000.000.000.000.000.000.000 Julios. El Sol tarda cerca de una semana en desprender esa energía. Piensa en eso. Para liberar esa cantidad de energía hacen falta aproximadamente 2.500.000.000.000 toneladas de antimateria. Eso asumiendo una pérdida nula de energía por calor y radiación, lo que es poco probable en la realidad: probablemente necesites 10 veces esa cantidad. Una vez que has generado la antimateria, llévala al espacio (si no la has creado allí) y lánzala contra la Tierra. La energía desprendida debería ser suficiente para romper la Tierra en miles de pedazos. Lo que queda de la Tierra: un segundo cinturón de asteroides alrededor del Sol. 6. Destruida por energía del vacío Necesitas: una bombilla. Método: Éste es divertido. Las teorías científicas contemporáneas nos dicen que lo que vemos como vacío es solamente vacío en media, y realmente es una cantidad de partículas y antipartículas apareciendo constantemente y cancelándose unas a otras. Ello nos sugiere que el volumen de espacio encerrado en una bombilla contiene suficiente energía de vacío para poner a hervir todos los océanos del mundo. Por lo tanto, la energía del vacío podría ser la fuente de energía más abundante. Ahí es donde entras tú. Todo lo que necesitas es saber cómo extraer esta energía y aprovecharla en algún tipo de central energética -se puede hacer fácilmente sin levantar demasiada sospecha- y entonces permitir clandestinamente que la reacción se descontrole. La liberación de energía resultante debería ser suficiente para destruir todo el planeta Tierra y posiblemente también el Sol. Ligeramente posible. Lo que queda de la Tierra: una nube de partículas de diferentes tamaños. 5. Absorbida por un agujero negro gigante. Necesitas: un agujero negro, motores de cohete extremedamente potentes y, opcionalmente, un gran cuerpo planetario rocoso. El agujero negro más cercano a nuestro planeta se encuentra a 1600 años luz, en dirección a Sagitario (V4641). Método: después de localizar tu agujero negro, necesitas unirlo a la Tierra. Este es posiblemente el paso que más tiempo lleva del plan. Hay dos métodos, moviendo la Tierra o moviendo el agujero negro, aunque para conseguir el mejor resultado deberías mover los dos a la vez. Muy, muy difícil, pero sin duda posible. Lo que queda de la Tierra: se convertiría en una parte de la masa del agujero negro. Fecha mínima de finalización: No se podría disponer de la tecnologá necesaria hasta, al menos, el año 3000; y hay que añadir al menos 800 años para el tiempo de viaje. (Eso en el marco de un observador externo de referencia y asumiendo que mueves la Tierra y el agujero negro al mismo tiempo). 4. Meticulosamente y sistemáticamente deshecha. Necesitas: una catapulta electromagnética, o mejor aún varias. Método: Básicamente, lo que vamos a hacer es ir arrancando de la Tierra grandes pedazos y ponerlos en órbita. La catapulta electromagnética fue propuesta como medio para transportar minerales de la Luna a la Tierra. Básicamente, solo necesitas cargar el trozo en la catapulta y disparar hacia arriba en la dirección correcta. Necesitaremos un pedazo suficientemente grande para superar la velocidad de escape de 11 kilómetros por segundo y lanzarlo hacia el Sol o arbitrariamente hacia el espacio. Otros métodos para expulsar el material al espacio son cargar los trozos en lanzaderas espaciales o subirlas con un ascensor espacial. Todos estos métodos, sin embargo, requieren de una cantidad enorme de energía para llevarse a cabo. Lo que queda de la Tierra: gran cantidad de trozos pequeños, algunos de los cuales caerían al Sol y los restantes se dispersarían por todo el Sistema Solar. Fecha mínima de finalización: Ah, si. Expulsando de la gravedad de la Tierra un billón de toneladas por segundo se tardaría 189.000.000 años en hacerla desaparecer. 3. Pulverizada por un impacto. Necesitas: una gran roca pesada. Podría servir… Marte. Método: Cualquier cosa puede ser destruida si la golpeas con la suficiente fuerza. Cualquier cosa. El concepto es simple: encuentra un asteroide muy, muy grande o un planeta, aceléralo a una velocidad enorme de tal manera que choque contra la Tierra, preferiblemente de frente. El resultado: una colisión espectacular que, con un poco de suerte, pulverizaría la Tierra. Ésta se convertiría en un número de trozos grandes, los cuales, si la colisión es fuerte, tendrían suficiente energía para superar su gravedad mutua y se alejarían para siempre. En otro caso, se volverían a convertir en un nuevo planeta. Vamos a hacer un breve análisis del tamaño del objeto que necesitamos. Cayendo a una velocidad mínima de impacto de 11 kilómetros por segundo y asumiendo una pérdida nula de energía en forma de calor o cualquier otra, el objeto debería tener aproximadamente el 60% de la masa de la Tierra. Marte, el planeta siguiente a la Tierra, tiene una masa de aproximadamente un 11% la de la Tierra, mientras que Venus, el planeta anterior y también el más cercano, tiene una masa del 81% de ésta. Asumiendo que la velocidad de impacto fuese mucho mayor que 11m/s (por ejemplo 50km/s) sería suficiente con una masa menor. Un asteroide de 10.000.000.000.000 toneladas al 90% de la velocidad de la luz sería suficiente. Bastante posible. Lo que queda de la Tierra: varios cachos de roca de aproximadamente el tamaño de la Luna, que se esparcirían por el Sistema Solar. Fecha mínima de finalización: 2500 quizás. 2. Devorada por una maquina de von Newman. Necesitas: una máquina de von Newman. Método: Una máquina de von Newman es cualquier dispositivo capaz de crear una copia exacta de el mismo sin nada excepto los materiales necesarios. Crear una de estas máquinas compuesta casi completamente de hierro, magnesio, aluminio y silicio, los materiales que más se encuentran en el manto y el núcleo de la Tierra. No importa cuánto de grande sea sino más bien que se pueda reproducir a ella misma cada período de tiempo. Colócala debajo de la corteza terrestre y deja que se reproduzca. Espera y verás como crea otra segunda máquina de von Newman. Entonces éstas crearán otras dos, y a su vez éstas otras cuatro y así sucesivamente. Como la cantidad de máquinas crece rápidamente, el planeta Tierra será devorado rápidamente y convertido en un enjambre de sixtrillones de máquinas. Técnicamente tu objetivo se habría cumplido -la Tierra ya no existe- pero si quieres ser minucioso puedes ordenar a las máquinas que se lancen, junto con cualquier elemento restante de la Tierra, hacia el Sol. Este lanzamiento se podría conseguir usando un cohete de propulsión o algo así, así que asegúrate de incluirlo en tu diseño de la máquina. Una idea tan disparatada que podría funcionar. Lo que queda de la Tierra: los cuerpos de las máquinas de von Newman y luego un pequeño pedazo de hierro hundiéndose en el Sol. Fecha mínima de finalización: 2045-2050 o incluso antes. 1. Lanzada hacia el Sol. Necesitas: equipo para mover la Tierra. Método: Lanza la Tierra hacia el Sol. Mandar a la Tierra para que colisione con el Sol no es tan fácil como podría parecer. Sería muy fácil que la Tierra acabase en una órbita elíptica, la cual haría que la Tierra se tueste durante cuatro meses de cada ocho. Pero ésto se podría evitar con un plan cuidadosamente diseñado. Es imposible con el actual nivel tecnológico, pero será posible algún día, estoy seguro. Mientras tanto, podría darse que algo que venga de la nada golpee aleatoriamente a la Tierra en la dirección correcta, produciendo el efecto deseado. Lo que queda de la Tierra: una pequeña esfera de hierro vaporizado hundiéndose lentamente en el corazón del Sol. Fecha mínima de finalización: Por medio de una actuación de Dios: 25 años. Podría suceder antes si se produce por el golpe mencionado anteriormente. Por medio de intervención humana: dado el actual nivel de progreso en la tecnología espacial: año 2250.

Amerykański akcelerator RHIC ma przeprowadzić szereg testów naruszających jego parametry techniczne. Dla niektórych jest to rażące nadużycie, bowiem nie wiadomo, czym to się skończy. Jednym z niepokojących scenariuszy jest wygenerowanie przez zderzacz „dziwadełek” - egzotycznych cząsteczek, które mogą zmienić Ziemię w „martwą i ultragęstą kulę o średnicy 100 m.”

The integrated elliptic flow of charged particles produced in Pb+Pb collisions at √sNN=2.76 TeV has been measured with the ATLAS detector using data collected at the Large Hadron Collider. The anisotropy parameter, v2, was measured in the pseudorapidity range |η|≤2.5 with the event-plane method. In order to include tracks with very low transverse momentum pT, thus reducing the uncertainty in v2 integrated over pT, a 1 μb−1 data sample recorded without a magnetic field in the tracking detectors is used. The centrality dependence of the integrated v2 is compared to other measurements obtained with higher pT thresholds. The integrated elliptic flow is weakly decreasing with |η|. The integrated v2 transformed to the rest frame of one of the colliding nuclei is compared to the lower-energy RHIC data

Abstract: The National Ignition Facility, sited at the Lawrence Livermore National Laboratory in Livermore, Calif., is a 192-beam, 1.8-MJ (351 nm) laser designed to compress ~250 µg spheres of deuterium and tritium to thermonuclear ignition. Fuel compression is achieved through an ablative rocket drive mechanism where the outer wall of the fuel shell is ablatively removed by a 300 eV radiation field. The 300 eV field is produced through laser matter interactions at the wall of either a gold or uranium hohlraum surrounding the capsule. Obtaining ignition will depend on controlling several critical aspects of the implosion, including the amount of kinetic energy transferred to the fuel, the internal energy generated within the fuel, the symmetry of the implosion, as well as maintaining the hydrodynamic stability of the fuel as it compresses. Imaging diagnostics provide unique insight into the performance of these implosions, and the NIF has assembled a broad suite of imaging capability, utilizing both X-rays and neutrons to diagnose critical aspects of the implosion process. In this presentation I will review the basic motivation for the inertial confinement fusion experiments taking place at the NIF, as well as a description of the NIF laser and its diagnostic capability, with an emphasis on imaging. This work was performed for the U.S. Department of Energy and National Nuclear Security Administration and by the National Ignition Campaign partners: Lawrence Livermore National Laboratory, University of Rochester Laboratory for Laser Energetics, General Atomics, Los Alamos National Laboratory and Sandia National Laboratories. Other contributors include Lawrence Berkeley National Laboratory; the Massachusetts Institute of Technology; Atomic Weapons Establishment, England; and Commissariat à l’Énergie Atomique, France. Gary P. Grim received his B.S. in mathematics from California State University, Chico in 1985, followed by his M.S. in 1992 and Ph.D. in 199) in experimental physics from the University of California, Davis. Grim’s graduate studies were in the field of particle physics, where he studied rare charm mesons decays as a test of electro-weak interaction theory within the standard model of particle physics. During his postdoctoral research in 1995–1999, Grim switched research groups at Davis and was an active participant in the design and construction of several semiconductor-based particle tracking detectors aimed at hadron collider experiments. These efforts included the CDF experiment at Fermi National Accelerator Laboratory and CMS experiment at CERN. During this time, Grim developed and tested the first data-driven pixel tracking telescope for use in high energy physics. In 2002, Grim joined the Physics Division staff at the Los Alamos National Laboratory. During his tenure at LANL, he has worked on a wide ranging set of projects and problems, including leading the design and construction of the National Ignition Facility neutron imaging diagnostic, as well as being a key player in the construction of a forward pixel detector for use at the PHENIX experiment at the RHIC facility sited at Brookhaven National Laboratory. Grim’s current efforts are focused on analyzing the data being produced by the NIF imaging diagnostics, as well as leading the development of new NIF diagnostic capabilities including the novel prompt-radiochemical assay techniques and gamma-ray imaging capabilities.

Abstract: A major ongoing research effort in nuclear and particle physics is focused in improving our understanding of the properties of matter under extreme conditions. A main goal is mapping the QCD phases at different regions of temperature and densities. At present, we know of (at least) three fundamental states of matter in QCD that exist in the extreme regions of temperature and/or density. They are the hadronic matter with broken chiral symmetry and quark confinement, the quark-gluon plasma, and the color superconductivity. Exploration of a wider range of the QCD phase diagram with densities up to several times the normal nuclear matter density is expected to be carried out in the near future at RHIC and at planned facilities all over the world (FAIR, NICA, J-PARC). The QCD phase diagram becomes even richer in the presence of a magnetic field. In this colloquium I will review our current understanding of the physical properties of quark matter at ultra-high density in the presence of very large magnetic fields and will mention some recent results in the region of intermediate densities.

The internal structure of the nucleon is more complicated than expected in a simple quark model. In particular, the portion of the nucleon spin carried by the spins of the quarks is not, as expected, of the order of one, but according to the experimental data much smaller. In this thesis we study the spin structure of the proton in quantum chromodynamics. The constituent quark model, based on SU(6), predicts that the spin of the proton should be carried by the quarks, in disagreement with the experiments. It appears strange, that the theoretical model works so well for the magnetic moments of the nucleons, but not for the spin, although the spin and the magnetic moments are closely related to each other. We shall resolve this problem by assuming that the constituent quarks have an internal structure on their own. Thus a constituent quark has a dynamical structure, and we can introduce notions like the quark or gluon distributions inside a constituent quark. In the light of new experimental data from HERMES, COMPASS, J-Lab, and RHIC-spin, the current status of our knowledge of the spin structure is discussed in the two theoretical frameworks: the naive parton model, and the QCD evolved parton model. QCD a is successful theory, both in perturbative and non-perturbative regions, but the spin of the nucleon still needs to be explained within QCD.

Abstract: My lecture will describe what is now known from experiments about the properties of strongly interacting matter at the highest accessible energy densities. The important pieces of evidence include: large collective flow, strong quenching of jets, and characteristic differences in the emission features of mesons and baryons. The matter produced in nuclear collisions thus reveals itself as a nearly inviscid fluid ("perfect liquid") of extreme SU(3)-color opaqueness. I will explain how these properties are related to each other and discuss what they may imply for the internal structure of the matter produced at RHIC. The lecture will conclude with a brief discussion of the main open questions to be addressed in future experimental and theoretical investigations. Presented April 20, 2007 Dr. Mueller is J. B. Duke Professor of Physics at Duke University. Dr. Mueller's research currently focuses on nuclear matter at extreme energy density. Quantum chromodynamics, the fundamental theory of nuclear forces, predicts that nuclear matter dissolves into quarks and gluons, the constituents of nucleons, when a critical energy density is exceeded. He and his collaborators are studying the properties of this quark-gluon plasma from the theoretical point of view. They are also developing the theory of the formation of a quark-gluon plasma and its possible detection in high-energy nuclear collisions.
