Book Neutral Pion Production in Nucleus nucleus Collisions at 158 and 200 GeV nucleon

Download or read book Neutral Pion Production in Nucleus nucleus Collisions at 158 and 200 GeV nucleon written by and published by . This book was released on 1998 with total page 11 pages. 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 Energy and Target Dependence of the Pseudo rapidity Distributions in Pion and Proton nucleus Collisions at Fermilab Energies

Download or read book Energy and Target Dependence of the Pseudo rapidity Distributions in Pion and Proton nucleus Collisions at Fermilab Energies written by and published by . This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiparticle production in hadron-nucleus collisions has been studied using hodoscope arrays. Data on angular distributions were collected for incident .pi./sup + -/, K/sup + -/, and P/sup + -/ at 50, 100, and 200 GeV with targets ranging from hydrogen through uranium. The extent in pseudo-rapidity of particles produced in the target fragmentation region increases with energy. Proton and pion induced reactions exhibit different behavior for the same target nucleus. However, for target nuclei with identical values of .nu.bar, (where .nu.bar is the average thickness in units of the mean free path of the incident particle) the behavior is similar. Pseudo-rapidity distributions are compared with theoretical models.

Book Nucleus nucleus Collisions at Ultra relativistic Energies

Download or read book Nucleus nucleus Collisions at Ultra relativistic Energies written by and published by . This book was released on 1995 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is based on three lectures presented at the Prague Seminar on Relativistic Heavy-Ion Physics in September 1994. The first lecture, following a general introduction, focuses on three different aspects of the CERN experiment WA80. The author first presents results on global event characteristics deduced primarily from measured distributions of transverse energy and of forward energy. The purpose is to introduce the main general features of nucleus-nucleus reactions at the highest energies currently available. He highlights the role of projectile-target geometry, discusses the degree of nuclear stopping, and estimates the energy densities attained in these reactions. This discussion is followed by a presentation of one of two topics that are unique to the WA80 experiment and which are not addressed by any of the other CERN collaborations that study nucleus-nucleus reactions: direct measurements of photons. The second topic unique to WA80, measurements of proton-proton correlations in the target-fragmentation region, is covered in the first part of the second lecture. The remainder of the second lecture is devoted to a selective overview of results obtained at the AGS accelerator of Brookhaven National Laboratory (BNL). The third lecture is devoted to a discussion of the two main experiments, STAR and PHENIX, planned for the Relativistic Heavy Ion Collider, RHIC, under construction at BNL.
