This book was released on 1990 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possibility of forming a quark-gluon plasma is the primary motivation for studying nucleus-nucleus collisions at very high energies. Various signatures'' for the existence of a quark-gluon plasma in these collisions have been proposed. These include an enhancement in the production of strange particles, suppression of J/[Psi] production, observation of direct photons from the plasma, event-by-event fluctuations in the rapidity distributions of produced particles, and various other observables. However, the system will evolve dynamically from a pure plasma or mixed phase through expansion, cooling, hadronization and freezeout into the final state particles. Therefore, to be able to determine that a new, transient state of matter has been formed it will be necessary to understand the space-time evolution of the collision process and the microscopic structure of hadronic interactions, at the level of quarks and gluons, at high temperatures and densities. In this talk I will review briefly the present state of our understanding of the dynamics of these collisions and, in addition, present a few recent results on particle production from the NA35 experiment at CERN. 21 refs., 5 figs.

Book excerpt: In experiments with oxygen (60 and 200 GeV/N) and sulphur (200 GeV/N) ions at CERNSPS, large energy densities of the order of 2--3 GeV/fm3 have been observed, which according to QCD calculations, satisfy necessary conditions for the formation of a quark gluon plasma (QGP) phase. Under such conditions, colour would no longer be confined to hadronic dimensions, and quarks and gluons will propagate freely throughout an extended volume. Somehow lower energy densities, of the order of 0.7--1 GeV/fm3, were observed in AGS experiments with 15 GeV/N silicon beams and heavy targets. These energy densities might be adequate for investigations of the pre-equilibrium stage, during which the momentum space distribution has been degradated from its initial value but is not yet thermal. First experimental results, available now, show promise of seeing signs of a new phase of matter. In this review the current status of the selective experimental results on strange-particle production, which are relevant to equilibration and QGP formation in nucleus-nucleus collisions, is presented.

Available in PDF, EPUB and Kindle. Book excerpt: Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1960s, it has been known that the protons and neutrons in nuclei are composed of more fundamental particles called quarks. To date, there is no evidence that quarks have a substructure. Experiments at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab, on Long Island, New York, study the particle emerging from very energetic collisions between heavy nuclei like gold (each made up of 197 protons and neutrons), and offer a unique means for investigating the properties of quarks and the particles associated with the forces between quarks. The most high-profile scientific breakthrough so far at the RHIC accelerator was the discovery of quark-gluon plasma (QGP). The existence of this new phase of matter had been predicted on theoretical grounds, and it is believed to have existed briefly during the first microsecond after the Big Bang. Its discovery was further confirmation of the Standard Model - a unified description of matter in terms of quarks, particles in the electron family (leptons), and the fields mediating their interactions. Until recently, the available evidence always pointed to a smooth transition between ordinary matter and QGP, unlike the familiar discontinuous change of state (phase transition) when ice turns to liquid water, or when liquid water turns to steam. Changes of phase like in water are called first-order phase transitions. Theorists had anticipated that the normal maximum energy of the RHIC accelerator is too high to observe a first- order phase transition, and they predicted that it might be seen at a lower energy. This insight prompted a multi-year effort at RHIC, known as the Beam Energy Scan (BES), to investigate a wide range of beam energies and search for such phenomena. One of the challenges that arise in interpreting BES measurements is to investigate if a bombarding energy exists where a maximum occurs in the nuclear compression during the early stages of the collision. Naively, one might expect compression to keep increasing indefinitely as the beam energy increases, but nuclei, even if they collide exactly head-on, will transparently pass through each other without stopping at the highest energies, and this counteracts the above- mentioned increase in nuclear compression. Therefore, there probably exists an optimum beam energy where compression is a maximum. Nuclear compression during a nucleus-nucleus collision cannot be measured experimentally, and a model calculation is needed. This thesis involves study of the nuclear transport model AMPT (A Multi-Phase Transport). More specifically, the goal is to study nuclear compression as a function of time during the collision at a given collision energy, extract the maximum compression, then study this maximum as a function of collision energy over the range of energies being scanned at RHIC. The basic computer code to implement the AMPT model is freely available for investigation by any interested user, but various modifications and pieces of additional code need to be developed in order to probe the specific questions of relevance to the scientific objectives explained above.
