Book excerpt: Both NA44 and EOS continue to publish high quality data on relativistic heavy ion collisions. The next leap in energy will be provided by BRAHMS at RHIC. Experiment NA44 has measured particle correlations of [pi]{sup {+-}}, K and protons and single particle distributions of [pi]{sup {+-}}, K{sup {+-}}, p, {anti p}, d and {anti d} for pA, SA and PbPb collisions at 450GeV/c, 200A·GeV and 158A·GeV for the p, S and Pb beams respectively. When the spectra are fitted to an exponential in m{sub T}, the inverse slopes increase as the system gets heavier and with increasing particle mass. For larger systems the baryon density at mid-rapidity increases implying more secondary collisions. These fuel a collective expansion and a boost in transverse momentum proportional to the mass as seen in the data. The EOS collaboration has continued to publish results from their large data set of heavy ion collisions at the BEVALAC. They plan to study the energy dependence of coalescence and flow by comparing results from NA44 and EOS.

Available in PDF, EPUB and Kindle. Book excerpt: Two years ago, at the 12th Winter Workshop on Nuclear Dynamics held here in Snowbird, the authors presented WA80 limits on direct photon production in 200-GeV 32S + Au collisions. It was found that the results were consistent (within 1[sigma]) with the absence of an excess of photons over those that can be accounted for by the two-photon decay branches of [pi]° and [eta] mesons and by the small photon contributions from other radiative decays. They are in the process of finalizing the direct-photon production results from collisions of lead nuclei at 158 GeV/nucleon. The author briefly discusses the status of the analysis and gives some preliminary results at the end of this talk. However, most of this presentation is concerned with a very different aspect of the photon measurements: distributions of neutral pions. In contrast to direct photons which probe initial collision conditions, hadrons, such as neutral pions, interact strongly and decouple late in the reaction evolution and, thus, provide information concerning the system at freeze out. Transverse momentum spectra at low and intermediate p{sub T} relate to thermodynamic and hydrodynamic descriptions of the hot, dense systems. In addition, the high-p{sub T} region reflects the hard-scattering regime and may help one understand initial-state particle production by forming a bridge to proton-proton and proton-nucleus results. It follows that it is essential that the [pi]° measurements cover a large p{sub T} range.

Book excerpt: Abstract: Quantum Chromodynamics predicts a phase transition from a state formed by hadrons to a plasma of deconfined quarks and gluons, the Quark Gluon Plasma, as a the energy density exceeds a critical value. This deconfined phase is believed to be the one in which the early universe existed in a time-scale [approx.] 10−5 s after the Big Bang. Ultrarelativistic Heavy Ion Collisions, like the ones that take place at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, reach energy densities above the critical value creating a deconfined phase of quarks and gluons that can be studied at the laboratory. This gives us the opportunity to study a phase of matter in the deconfined region of QCD, the properties of the strong interaction, the formation of hadronic matter and the interaction between hadrons. In the analysis presented in this thesis, the dynamical evolution of the particle emitting source and its space-time structure at freeze-out is studied using the two particle intensity interferometry technique. The expansion of the source is also studied. We find indications that this expansion may be caused by the initial pressure gradient generated in the initial stages of the collision through particle rescattering in a very dense medium.
