Available in PDF, EPUB and Kindle. Book excerpt: A general review of experimental data on pion production in A-A collisions for incident energies below a few GeV/nucleon is presented. Early data on inclusive pion spectra, which served as the genesis for present pion measurements, are discussed. The majority of the paper is devoted to present pion experiments, with an emphasis being placed on what such experiments tell about the general features of high-energy A-A collisions. Particular attention is given to multipion production as studied in recent streamer chamber experiments. The review ends with projections on future experiments with the heavier beams that will be available in 1982 at Berkeley, and the higher-energy beams that will hopefully be available in the not too distant future. 39 figures.

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: A survey experiment of pion production at 180° in nucleus-nucleus collisions is presented. Beams of 1.05 GeV/A and 2.1 GeV/A protons, alphas, and carbon were used, as well as proton beams of 0.80 GeV, 3.5 GeV, and 4.89 GeV, and argon beams of 1.05 GeV/A and 1.83 GeV/A. This is the first such experiment to use the heavier beams. Targets used ranged from carbon to lead. An in-depth review of the literature, both experimental and theoretical, is also presented. The systematics of the data are discussed, and comparisons are made both with prior experiments and with the predictions of the models reviewed. The cross sections appear consistent with a simple single nucleon-nucleon collision picture, without the need for collective or other exotic effects. Suggestions for future work are made.

Download or read book Multiple Pion Production in ? -Ne Collisions at 10.5 and 200 GeV. written by and published by . This book was released on 1975 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have measured the multiplicities of pions produced in the collisions of ? mesons with neon nuclei at bombarding momenta of 10.5 and 200 GeV/c. The diffractive production of pions is clearly separable. If one excludes the diffractive part, the pion multiplicity obeys the same Koba-Nielsen-Olesen scaling as found previously for ?--p collisions. This fact would seem to indicate the validity of an energy-flux or collective-variable description of the production process. A surprisingly large number of energetic protons (> 1 GeV/c lab momentum) are found to be produced in ?-Ne collisions.

Book Synopsis Pion Production in 4.5 GeV Au + Au Collisions from the STAR Fixed-target Pilot Run by : Kathryn Carson Meehan

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The RHIC Beam Energy Scan (BES) Program was proposed to look for the turn-off of signatures of the quark gluon plasma (QGP), search for a possible QCD critical point, and study the nature of the phase transition between hadronic and partonic matter. The first phase of the BES program (BES-I) took place from 2010-2016. Several interesting observables studied in BES-I, including the net-proton higher moments and the directed flow of protons, show interesting behavior below 20 GeV and could suggest a transition to a hadron dominated regime. Data from energies lower than 7 GeV could help determine whether these behaviors are indicative of phase transitions or criticality. The goal of the STAR Fixed-Target (FXT) Program is to extend the collision energy range in BES-II to lower energies than is feasible with colliding beams. In order for this program to be approved, it was necessary to demonstrate that STAR could successfully perform measurements in a fixed-target geometry. In this dissertation we present results from the fixed-target pilot run data set collected in 2015 with the STAR detector. The pilot run consisted of 4.5 GeV per nucleon center-of-mass energy Au + Au collisions. The [pi]− spectra and rapidity density are measured from the top 5% most central collisions and found to be comparable to previous results at similar energies from the AGS experiments. Additionally the 4[pi] yield is extracted and found to be 153 +/- 15 (stat) +/- 29 (sys). Together, these and additional results measured by other analyzers from multiple institutions in STAR, demonstrated that STAR can successfully reproduce many physics results from the AGS experiments. This helped convince the Brookhaven Program Advisory Committee (PAC) to include an official FXT program in BES-II, to be conducted in 2019-2021. Specifically, the PAC approved the collection of 100 million events each taken at eight different energies with STAR operating in the fixed-target configuration. This will extend BES-II to center-of-mass energies as low as 3.0 GeV per nucleon, nearly doubling the [mu][subscript B] reach of the BES program and thus broadening our search for interesting transition features in the phase diagram.
