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.

Available in PDF, EPUB and Kindle. Book excerpt: This is the final technical report for DOE Outstanding Junior Investigator (OJI) Award, 'Systematic Studies of Heavy Ion Collisions to Search for Quark-Gluon Plasma', grant DE-FG02-02ER41219, Principal Investigator (PI) Fuqiang Wang. The research under the grant was divided into two phases. The first concentrated on systematic studies of soft hadron production at low transverse momentum (p{sub T}), in particular the production of (anti- )baryon and strangeness in heavy ion collisions at RHIC energies. The second concentrated on measurements of di-hadron and multi-hadron jet-correlations and investigations of medium response to jets. The research was conducted at the Relativistic Heavy-Ion Collider (RHIC) at BNL with the Solenoidal Tracker At RHIC (STAR) experiment. The total grant is $214,000. The grant established a PC farm solely used for this research. The PC farm consists of 8 nodes with a total of 16 CPUs and 3 disk servers of total 2 TB shared storage. The current balance of the grant is $19,985. The positive balance is because an initial purchase of $22,600 for the PC farm came out of the PI's start-up fund due to the lateness of the award. The PC farm is an integral part of the Purdue Physics Department's computer cluster. The grant supported two Ph. D. graduate students. Levente Molnar was supported from July 2002 to December 2003, and worked on soft hadron production. His thesis title is Systematics of Identified Particle Production in pp, d-Au and Au-Au Collisions at RHIC Energies. He graduated in 2006 and now is a Postdoctoral fellow at INFN Sezione di Bari, Italy working on the ALICE experiment at the LHC. Jason Ulery was supported from January 2004 to July 2007. His thesis title is Two- and Three-Particle Jet-Like Correlations. He defended his thesis in October 2007 and is moving to Frankfurt University, Germany to work on the ALICE experiment at the LHC. The research by this grant resulted in 7 journal publications (2 PRL, 1 PLB, 1 PRC, 2 submitted and 1 in preparation), and 14 invited talks and 10 contributed talks at major conferences. These are listed at end of this report.
Download or read book Study of Quark Gluon Plasma By Particle Correlations in Heavy Ion Collisions written by Li Yi and published by Springer. This book was released on 2016-08-25 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis covers several important topics relevant to our understanding of quark-gluon plasma. It describes measurement of the third-order harmonic flow using two-particle correlations and isolation of flow and non-flow contributions to particle correlations in gold-gold collisions. The work also investigates long-range longitudinal correlations in small systems of deuteron-gold collisions. The former is related to the hydrodynamic transport properties of the quark-gluon plasma created in gold-gold collisions. The latter pertains to the question whether hydrodynamics is applicable to small systems, such as deuteron-gold collisions, and whether the quark-gluon plasma can be formed in those small-system collisions. The work presented in this thesis was conducted with the STAR experiment at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, where the center-of-mass energy of both collision systems was a factor of 100 larger than the rest mass of the colliding nuclei. The results contained in this thesis are highly relevant to our quest for deeper understanding of quantum chromodynamics. The results obtained challenge the interpretation of previous works from several other experiments on small systems, and provoke a fresh look at the physics of hydrodynamics and particle correlations pertinent to high energy nuclear collisions.

This book was released on 2002-09-23 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the unique possibility of tackling the problem of hadronic deconfinement from different perspectives. After general introductions to the physical issues, from both the theoretical and the experimental point of view, the book presents the most recent expertise on field theory approaches to the QCD phase diagram, many-body techniques and applications, the dynamics of phase transitions, and phenomenological analysis of relativistic heavy ion collisions.One of the major goals of this book is to promote interchange among those fields of research, which have traditionally been cultivated by different communities of physicists. The contributions in the book help in obtaining deep comprehension of this new state of matter, a system of deconfined quarks and gluons. At the same time the book offers a few examples of how the seeds of the deconfined state are looked for in the phenomenological analysis of the observables measured in relativistic heavy ion collisions. The main topics are dealt with in a pedagogical style, suitable for beginners as well as experienced researchers.

Book excerpt: This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The authors used several complimentary models of high-energy nuclear collisions to systematically study the large body of available data from high energy (p{sub beam}/A> 10 GeV/c) heavy ion experiments at BNL and CERN and to prepare for the data that will come from RHIC. One major goal of this project was to better understand the space-time history of the excited hadronic matter formed in these collisions and to use this understanding to improve models of this process. The space-time structure of the system can be extracted from measurements of single-particle p{sub T} distributions and multiparticle correlations. They looked for experimental effects of the formation of the quark-gluon plasma. Understanding the hadronic phase of the interaction determines the sensitivity of experimental measurements to the presence of this exotic state of matter.

This book was released on 2024-02-28 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third book on Quark-Gluon plasma and heavy ion collisions follows the previous ones, published in 1988 and 2005, that described theoretical proposals for a large program, and then the QGP discovery at RHIC.The present one describes the rather mature field, with extensive program at RHIC and LHC colliders and corresponding theory. QGP turns out to be a strongly coupled medium made up of quarks and gluons, existing in exploding fireballs. It is the hottest form of matter created in a laboratory. Other subjects discussed in the book are QCD vacuum structure, including topological solitons and nonperturbative phenomena. It also includes some recent progress in theory of hadrons, bridging hadronic spectroscopy with partonic observables.

Download or read book Quark Gluon Plasma written by Tapan K. Nayak and published by . This book was released on 2014-11-30 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: At extremely high temperatures and densities, protons and neutrons may dissolve into a "soup" of quarks and gluons, called the Quark-Gluon Plasma (QGP). For a few microseconds, shortly after the Big Bang, the Universe was filled with the QGP matter. The search and study of Quark-Gluon Plasma (QGP) is one of the most fundamental research topics of our times. The QGP matter has been probed by colliding heavy ions at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, New York and the Large Hadron Collider at CERN, Geneva. By colliding heavy-ions at a speed close to that of light, scientists aim to obtain - albeit over a tiny volume of the size of a nucleus and for an infinitesimally short instant - a QGP state. This QGP state can be observed by dedicated experiments, as it reverts to hadronic matter through expansion and cooling. This volume presents some of the current theoretical and experimental understandings in the field of QGP.

Available in PDF, EPUB and Kindle. Book excerpt: Written primarily for researchers and graduate students who are new in this emerging field, this book develops the necessary tools so that readers can follow the latest advances in this subject. Readers are first guided to examine the basic informations on nucleon-nucleon collisions and the use of the nucleus as an arena to study the interaction of one nucleon with another. A good survey of the relation between nucleon-nucleon and nucleus-nucleus collisions provides the proper comparison to study phenomena involving the more exotic quark-gluon plasma. Properties of the quark-gluon plasma and signatures for its detection are discussed to aid future searches and exploration for this exotic matter. Recent experimental findings are summarised.

Available in PDF, EPUB and Kindle. Book excerpt: This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). We have developed field theory and numerical methods for the general problem of quantum back reaction on classical fields, with applications to a wide variety of physical systems. Our main focus was on particle production processes in the time evolution of the quark-gluon plasma following an ultrarelativistic heavy-ion collision. In particular, we studied in some detail the evolution of a disoriented chiral condensate (DCC) produced in the chiral phase transition of nuclear matter in heavy-ion collision experiments. We have also studied dissipation and decoherence as a result of particle production in time-varying mean fields. Numerical codes previously developed for particle production in strong electric fields in quantum electrodynamics (QED) have been modified for the quantum chromodynamics (QCD) problem. We have made specific predictions for energy-momentum flow and pion production in the central rapidity region of experiments to be performed at the Relativistic Heavy-Ion Collider (RHIC).
