Midrapidity Production of Secondaries in pp Collisions at RHIC and LHC Energies in the Quark-Gluon String Model

Abstract

We consider the phenomenological implications of the assumption that baryons are systems of three quarks connected through gluon string junction. The transfer of baryon number in rapidity space due to the string junction propagation is considered in detail. At high energies this process leads to a significant effect on the net baryon production in hN collisions at mid-rapidities. The numerical results for midrapidity inclusive densities of different secondaries in the framework of the Quark-Gluon String Model are in reasonable agreement with the experimental data. One universal value lambda ~ 0.25 for the strangeness suppression parameter correctly describes the yield ratios of Lambda/p, Xi/Lambda, and Omega/Xi. The predictions for pp collisions at LHC energies are also presented.
