Available in PDF, EPUB and Kindle. Book excerpt: Single particle inclusive spectra are presented for pion and kaon production in Si+Au reactions at an incident momentum of 14.6 A · GeV/c and Au+Au reactions at an incident momentum of 11.6 A · GeV/c. A simple geometric scaling of the pion production for central collisions as A{sub proj}13 and A{sub targ}23 results from the observed production of about one pion per participant. Kaon yields are shown to be proportional to the number of excited participants and consistent with RQMD and ARC calculations.

Book excerpt: The inclusive kappa production cross sections were measured at angles from 15 to 80° in collisions of protons (2.1 GeV) and deuterons (2.1 GeV/amu) on NaF and Pb, and Ne (2.1 GeV/amu) on C, NaF, KCl, Cu, and Pb. The kaons were identified by measuring the time of flight and the momentum in a magnetic spectrometer, and by detecting the particles from the kaon decays in a Pb glass Cerenkov counter. The momentum range of the detected kaons extended from 350 MeV/c to 750 MeV/c. The multiplicity of each event was measured by a set of scintillation counter telescopes which were situated around the target. The differential cross section of the kaons falls off exponentially with center of mass energy in the nucleon nucleon center of mass frame. In addition, the angular distribution of the kaons is nearly isotropic in this frame even for p−1 NaF and Ne−1 Pb collisions. The data are compared with a row on row model and a thermal model. Neither are able to explain all features of the data. The row on row model does not reproduce the near isotropy in the nucleon nucleon frame, and the thermal model overpredicts the kaon yield by a factor of approximately twenty.

Available in PDF, EPUB and Kindle. Book excerpt: Preliminary results from E-802 (Si-beam) and B-866 (Au-beam) are presented for central collisions. Meson production ([pi]'s and K's) in heavy ion collisions are discussed from light systems (A = 55) to heavy systems (A = 394). Comparisons with predictions of the cascade code ARC are carried out. The balance of energy and momentum is considered for the Au+Au data.

Available in PDF, EPUB and Kindle. Book excerpt: We discuss the production of particles in relativistic heavy-ion collisions through the mechanism of massive bremsstrahlung, in which massive mesons are emitted during rapid nucleon acceleration. This mechanism is described within the framework of classical hadrodynamics for extended nucleons, corresponding to nucleons of finite size interacting with massive meson fields. This new theory provides a natural covariant microscopic approach to relativistic heavy-ion collisions that includes automatically spacetime nonlocality and retardation, nonequilibrium phenomena, interactions among all nucleons, and particle production. Inclusion of the finite nucleon size cures the difficulties with preacceleration and runaway solutions that have plagued the classical theory of self-interacting point particles. For the soft reactions that dominate nucleon-nucleon collisions, a significant fraction of the incident center-of-mass energy is radiated through massive bremsstrahlung. In the present version of the theory, this radiated energy is in the form of neutral scalar ([sigma]) and neutral vector ([omega]) mesons, which subsequently decay primarily into pions with some photons also. Additional meson fields that are known to be important from nucleon-nucleon scattering experiments should be incorporated in the future, in which case the radiated energy would also contain isovector pseudoscalar ([pi], [pi]−, [pi]°), isovector scalar ([delta]+, [delta]−, [delta]°), isovector vector ([rho]+, [rho]−, [rho]°), and neutral pseudoscalar ([eta]) mesons.

Its primary goals are studies of highly excited matter and its production in nuclear collisions at very high energies. After a general orientation on the project, abstracts describing the contents of completed papers and providing some details of current projects are given. Principal topics of interest are the following: the dynamics of nuclear collisions at very high energies (RHIC and LHC), the dynamics of nuclear collisions at AGS energies, high-temperature QCD and the physics of the quark-gluon plasma, and the production of strangelets and other rare objects.

This book was released on 1992 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental work is reported on the following topics: transverse energy production in 10.7-GeV/c/u Au on Au collisions; first results on delta ray production and charged particle multiplicities with the Au beam at 10.7 GeV/c/A; preliminary studies on the feasibility of flow measurement with the E814 participant calorimeter; preliminary results from the E877 telescope; and low-p[sub t] baryon distribution in Si+Al, Pb collisions at the AGS. Then the status of the Hadronic Calorimeter project of AGS Experiment E864 (ECOS--Exotic Composite Object Spectrometer) is reviewed. Next, the same is done for work of the STAR RHIC collaboration (Silicon Vertex Tracker (SVT) project evolution and development in FY92, SVT software results from 1992, SVT instrumentation, FY93 SVT pion test beam). The instrumentation section deals with the design and installation of a target rapidity telescope for BNL experiment 814/877 and a repair scheme for the E814/E877 participant calorimeter. Finally, the theory part addresses bosonic kinetics: thermalization of mesons and the pion p[sub perpendicular] spectrum in ultrarelativistic heavy-ion collisions and non-equilibrium properties of hadronic mixtures.

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.
