Proton and Λ hyperon production in nucleus-nucleus collisions

Abstract

The experimental data on net proton and net Λ-hyperon spectra obtained by the NA35 Collaboration, as well as the inclusive densities of Λ andΛ obtained by NA49, NA57, and STAR collaborations, are compared with the predictions of the QuarkGluon String Model. The contributions of String Junction diffusion, interactions with nuclear clusters, and the inelastic screening corrections are accounted for. The level of numerical agreement of the calculations with the experimental data is of about 20−30%. The predictions for LHC are also presented.PACS. 25.75.Dw Particle and resonance production 1

Centrality dependence of antihyperon production in heavy-ion collisions at high energies

“…The QGSM provides a succesful thorough description of multiparticle production processes in hadron-hadron [3], hadron-nucleus [4], and nucleus-nucleus [5] collisions, for a wide energy region.…”

Centrality dependence of multistrangeness production in high-energy heavy-ion collisions

“…The QGSM provides a succesful thorough description of multiparticle production processes in hadron-hadron [9][10][11][12][13], hadron-nucleus [14][15][16], and nucleus-nucleus [17][18][19][20] collisions, for a wide energy region. In particular, the inclusive spectra of charged pions, kaons, nucleons, and Λ hyperons, were correctly described in the cited papers.…”

Multistrange Hyperon Production on Nuclear Targets

“…The QGSM provides a succesful thorough description of multiparticle production processes in hadron-hadron [9,10,11,12,13], hadron-nucleus [14,15,16], and nucleusnucleus [17,18,19,20] collisions, for a wide energy region. In partcular, the inclusive spectra of charged pions, kaons, nucleons, and Λ hyperons, were correctly described in the cited papers.…”
