This book was released on 1997-10-13 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume gives a consistent overview of various theoretical and experimental programs which study the dynamics of nucleus-nucleus collisions from low to ultra-relativistic energies. The contributions concentrate on the following topics: cold fragmentation of nuclear matter, pre-equilibrium and thermalization, thermal and chemical equilibration, fragmentation and correlations in intermediate energy collisions, dynamical properties of hot and dense nuclear matter in medium effects, resonance and strange nuclear matter, and signals of the deconfined state.High quality data obtained using experimental devices close to 4π geometries and recent theoretical developments are presented. They illustrate the significant progress made during the last few years in understanding the properties of nuclear matter in extreme conditions of pressure and temperature.This book serves as a graduate textbook and as a reference work on recent developments in this area.

KARSCH and published by . This book was released on 2006 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: At high temperatures or densities matter formed by strongly interacting elementary particles (hadronic matter) is expected to undergo a transition to a new form of matter--the quark gluon plasma--in which elementary particles (quarks and gluons) are no longer confined inside hadrons but are free to propagate in a thermal medium much larger in extent than the typical size of a hadron. The transition to this new form of matter as well as properties of the plasma phase are studied in large scale numerical calculations based on the theory of strong interactions--Quantum Chromo Dynamics (QCD). Experimentally properties of hot and dense elementary particle matter are studied in relativistic heavy ion collisions such as those currently performed at the relativistic heavy ion collider (RHIC) at BNL. We review here recent results from studies of thermodynamic properties of strongly interacting elementary particle matter performed on Teraflops-Computer. We present results on the QCD equation of state and discuss the status of studies of the phase diagram at non-vanishing baryon number density.

Available in PDF, EPUB and Kindle. Book excerpt: Results for (Lambda) production by gold beams on gold targets were analyzed and published. The author completed the analysis of the Si-Si and Si-Lead data from previous runs. The results have been published in a series of papers. Major components of the STAR detector for RHIC have been built and have arrived at BNL. The detector continues to evolve and work continues on developing programs for the detector and simulating events and physics results that will be seen by it. The move is underway from design to physical construction to test and commissioning and some of the detector is taking shape. Much of the effort in the past year has gone into refining the detector design, looking at possible triggers, and developing a software system for simulating and eventually analyzing events. Building, commissioning, and operating this detector (including the software) will be a major effort over the coming years. The author studied the E810 Si-Pb full field data for positive-negative track correlations. He estimated the number of excited nucleons (N*'s) and Deltas in their region of measurement. From the relative population of ground state nucleons (pn, n) and excited nucleons he determined the freeze-out temperature of the hot system created in a high energy, heavy ion collision. Prof. Kramer was involved in the overall program for E881 and primarily in the software development for STAR while Mr. Efstathiadis had concentrated on understanding the data, i.e. primarily developing Monte Carlo programs to gain insight into the mechanisms important in the collisions and corrections needed in the analysis. The latest versions of GEANT were used to simulate the E891 apparatus and special programs were developed to be able to easily input STAR detector geometries into GEANT.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Heavy ion collisions conducted at the Relativistic Heavy Ion Collider (RHIC) and the LargeHadron Collider (LHC) are sufficiently energetic to create a deconfined state of quarks andand gluons known as Quark Gluon Plasma (QGP). In the infinite momentum limit, thereis a longitudinal symmetry, known as boost invariance, that reduces the dynamics to 2+1-dimensions, simplifying simulations and allowing for detailed study of the transverse dy-namics of heavy ion collisions. Boost invariance is only an approximation, however, and acomplete understanding must come from the full 3+1D dynamics of heavy ion collisions. Inthis thesis, the phenomenologically successful IP-Glasma model [1, 2] for the initial state ofheavy ion collisions is generalized to 3+1D using JIMWLK rapidity evolution [3, 4] of thepre-collision Wilson lines. The initial gauge fields for the individual nuclei are modified to bepure gauge outside of the source terms in all three spatial directions in order to avoid energydeposition outside of the interaction region between the two nuclei. Additionally, Gauss’law is no longer trivially satisfied in 3+1D, and must be satisfied locally. An ansatz anditerative solution to Gauss’ law is introduced. The effect of these modifications is exploredon the evolution of the chromo-electric and chromo-magnetic fields, as well as the pressurein the IP-Glasma phase. Most importantly, these modifications allow for self-consistent tem-poral evolution of the Classical Yang Mills equation of motion on a 3D lattice and thusfor phenomenological application. The 3+1D IP-Glasma initial state is coupled to 3+1Drelativistic viscous hydrodynamics using the MUSIC numerical software [5], which is in turnmatched to the hadronic cascade model UrQMD [6]. This hybrid model is used to study theinitialization and evolution of Pb-Pb collisions at s =√2.76 TeV in 3+1D, providing thefirst opportunity to study the phenomenological consequences of the JIMWLK renormaliza-tion group equation on the longitudinal dynamics of heavy ion collisions and the resultingparticle spectra"--

Available in PDF, EPUB and Kindle. Book excerpt: The quark-gluon plasma (QGP) has been produced by relativistic heavy ion collisions, and understanding its properties is a primary goal in the field of nuclear physics. This research first elucidates recent semianalytical developments that improve the estimates of the initial energy and net conserved-charge densities and enable the calculation of trajectories in the quantum chromodynamics (QCD) phase diagram for the matter produced by nuclear collisions. A semianalytical model of the initial densities is developed by including the finite nuclear thickness for parton production. The new maximum energy density is found to have an analytical upper bound and satisfy an approximate scaling relation. QCD phase diagram trajectories are extracted from the semianalytical densities using several nuclear equations of state, and the calculated QGP lifetimes are found to depend significantly on the values of the model's parameters. The study next presents a comparison between two solutions of the relativistic Boltzmann equation (RBE): one, a numerical solution using parton trans- port; the other, a theoretical solution for a homogeneous gas of massless particles. Parton transport in Zhang's parton cascade (ZPC) is found to reproduce the results of a recent ex- act analytical solution of the RBE with an unexpected effectiveness at high densities when using new generalized collision schemes. Finally, the work discusses some open questions related to parton transport in ZPC and suggests some possible directions to uncover their answers. These future research goals include discovering the cause of an unexpected problem arising in simulations with three-dimensional (3D) expansion, understanding the theoretical distribution of the total center-of-mass (CM) energy squared for two-parton collisions, and studying curved parton motion in the presence of strong electromagnetic fields. Overall, the results presented in this dissertation improve the theoretical and numerical descriptions of the QGP and should be useful for future studies.

Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to cover the fascinating field of physics of relativistic heavy ions, mainly from the experimentalist's point of view. After the introductory chapter on quantum chromodynamics, basic properties of atomic nuclei, sources of relativistic nuclei, and typical detector set-ups are described in three subsequent chapters. Experimental facts on collisions of relativistic heavy ions are systematically presented in 15 consecutive chapters, starting from the simplest features like cross sections, multiplicities, and spectra of secondary particles and going to more involved characteristics like correlations, various relatively rare processes, and newly discovered features: collective flow, high pT suppression and jet quenching. Some entirely new topics are included, such as the difference between neutron and proton radii in nuclei, heavy hypernuclei, and electromagnetic effects on secondary particle spectra.Phenomenological approaches and related simple models are discussed in parallel with the presentation of experimental data. Near the end of the book, recent ideas about the new state of matter created in collisions of ultrarelativistic nuclei are discussed. In the final chapter, some predictions are given for nuclear collisions in the Large Hadron Collider (LHC), now in construction at the site of the European Organization for Nuclear Research (CERN), Geneva. Finally, the appendix gives us basic notions of relativistic kinematics, and lists the main international conferences related to this field. A concise reference book on physics of relativistic heavy ions, it shows the present status of this field.

Book excerpt: The overall goal of this project is to study nucleus-nucleus collisions experimentally at intermediate and relativistic energies, with emphasis on measurement and interpretation of correlation effects that provide insight into the nuclear phase diagram and the nuclear equation of state. During the past year, the PI has been on leave at Lawrence Berkeley Lab and has worked on this research project full-time. A large fraction of the effort of the PI and graduate students has gone into preparing for experiments using the Time Projection Chamber at LBL's Bevalac accelerator; in March 1992, this device successfully took data in production mode for the first time, and the first physics analysis is now under way. The PI has carried out simulations that help to define the physics performance and engineering specifications of the recently-approved STAR detector for the Relativistic Heavy Ion Collider, and has identified a new capability of this device with the potential for being an important quark-gluon plasma signature. A Postdoctoral Fellow, jointly supported by this grant and Kent State University, has been recruited to augment these efforts. Since May 1991, 11 journal papers have been published or submitted for publication; 2 conference proceedings and 9 reports or abstracts have also been published during the past year. One paper in Phys. Rev. Left., one in Phys. Rev. C, and one conference proceedings are based on the thesis project of one of the PI's Ph. D. students who is expected to graduate later this year. Partly in response to the impending closure of the Bevalac, the PI's group has recently joined the NA49 experiment at CERN.
