Download Centrality and Collision System Dependence of Antiproton Production from P+A to Au+Au Collisions at AGS Energies Book in PDF, ePub and Kindle
Antiproton production in heavy ion collisions reflects subtle interplay between initial production and absorption by nucleons. Because the AGS energies (10--20 A·GeV/c) are close to the antiproton production threshold, antiproton may be sensitive to cooperative processes such as QGP and hadronic multi-step processes. On the other hand, antiproton has been proposed as a probe of baryon density due to large N{anti N} annihilation cross sections. Cascade models predict the maximum baryon density reaches about 10 times the normal nucleus density in central Au+Au collisions, where the strong antiproton absorption is expected. In this paper, the authors show systematic studies of antiproton production from p+A to Au+Au collisions.

The third course of the International School on Physics with Low Energy Antiprotons was held in Erice, Sicily at the Ettore Majorana Centre for Scientific Culture, from 10 to 18 June, 1988. The School is dedicated to physics accessible to experiments using low energy antiprotons, especially in view of operation of the LEAR facility at CERN with the upgraded antiproton source AAC (Antiproton Accumulator AA and Antiproton Collector ACOL). The first course in 1986 covered topics related to fundamental symmetries; the second course in 1987 focused on spectroscopy of light and heavy quarks. This book con tains the Proceedings of the third course, devoted to the experimental and theoretical aspects of the interaction of antinucleons with nucleons and nuclei. The Proceedings contain both the tutorial lectures and contributions presented by participants during the School. The papers are organized in several sections. The first section deals with the theoretical aspects of NN scattering and annihilation, and the underlying QCD. The experimental techniques and results concerning NN scattering are contained in Section II. Section III contains theoretical reviews and contributions on anti proton-nucleus scattering and bound states. Section IV is devoted to the experimental results on the antiproton nucleus systems and their phenomenological analysis. Finally, some possible developments of the antiproton machines are presented.

We present antiproton invariant multiplicities from Experiment 941 using 12 and 19 GeV/c proton beams incident upon targets of Pb, Cu and Be. Since we are currently unable to calculate antiproton yields in this regime from first principles, we must rely on empirical data in order to answer questions involving antibaryon production at these energies. Typically, the motivation for studying this topic using proton-nucleus (p-A) collisions is to shed light on antiproton production in the more complicated collisions between heavy nuclei (A-A). For this reason, this thesis will use the measured target dependence to illuminate issues relating to annihilation of antiprotons in the nuclear medium. It is found that, at 19 GeV/c beam momentum, the ratio of the antiproton invariant multiplicities in lead divided by those in beryllium is less than one and suggests strong antiproton annihilation in the lead target. Furthermore, the target dependence does not disappear as the antiproton's relative momentum with respect to the nucleus increases, which may suggest that the antiproton often rescatters without annihilating in the heavier target. A simple Glauber model is employed to quantify the absorption in the nucleus. In addition, comparisons will be made with the antiproton production in E941's predecessor experiment, E864. The energy scaling observed by E941 will assist in the comparison of our data to E864 and other experiments.
