Particle Production at Large Transverse Momentum in Nucleus-nucleus Collisions*
Based on a multiple hard scattering picture we derived simple relations between inclusive cross sections for large transverse momentum particle production in nucleus-nucleus, nucleon-nucleus and nucleonnucleon scatterings. The relations are compared with the recent data for 1~' production in aa collisions at high energy. Submitted to Physical Review D * Work supported in part by the Department ...
متن کاملSubthreshold 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 ...
متن کاملcharm 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...
متن کاملCharmonium 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...
متن کاملIdentified Particle Production at High Transverse Momentum in Nucleus-nucleus Collisions at Rhic
Experimental results for identified hadron spectra in AA collisions at RHIC are reviewed. Jet suppression in central AuAu collisions at 200 GeV is seen in leading meson and baryon spectra at high pt. Enhanced baryon production at intermediate pT (2 < pt < 5 GeV/c) is related to quark content but not its mass. In d+Au collisions Cronin enhancement is observed with larger magnitude for baryons th...
