Subthreshold antiproton production in nucleus-nucleus collisions.

Antiproton production from the secondary process pp~ pp is studied for nucleus-nucleus collisions at energies which are below the threshold for its production from the nucleon-nucleon reaction in the free space. In an expanding fireball model, we determine the p abundance from the fusion of pions and find that for collisions at 2. 1 GeV/nucleon the antiproton to negative pion ratio is = 5.5&10 ...

charm production in relativistic nucleus - nucleus collisions ∗

We calculate excitation functions for open charm mesons in Au + Au reactions from AGS to RHIC energies within the HSD transport approach which is based on string, quark, diquark (q, ¯ q, qq, ¯ q ¯ q) and hadronic degrees of freedom. The open charm cross sections from pN and πN reactions are fitted to results from PYTHIA and scaled in magnitude to the available experimental data. From our dynami...

Charmonium Production in Nucleus-Nucleus Collisions

This is a review of theoretical attempts to describe production of heavy quark bound states in nucleus-nucleus collisions, in particular, the relative suppression of J/ψ and ψ production observed in these reactions. The review begins with a survey of experimental data for proton-induced reactions and their theoretical interpretation. The evidence for additional suppression in nucleus-nucleus co...

Strangeness production in antiproton-nucleus annihilation

Abstract. The results of the microscopic transport calculations of p̄-nucleus interactions within a GiBUU model are presented. The dominating mechanism of hyperon production is the strangeness exchange processes K̄N → Yπ and K̄N → ΞK. The calculated rapidity spectra of Ξ hyperons are significantly shifted to forward rapidities with respect to the spectra of S = −1 hyperons. We argue that this shif...

PK)N PRODUCTION IN NUCLEUS-NUCLEUS COLLISIONS* LSSchroeder

Current work on pion production in high-energy nucleus-nucleus collisions is re­ viewed. The majority of existing data are of the inclusive variety in which a single final state pion is detected. Experimental data are compared and their possible con­ tributions to obtaining new information on nuclear structure is discussed. Various models which attempt to explain the observed singlc-inclusive-p...
