Midrapidity hyperon production in pp and pA collisions from low to LHC energies

TL;DR

Contribution

It introduces extended Quark-Gluon String Model calculations that incorporate new effects and predict hyperon spectra at LHC energies.

Findings

Model successfully describes existing data

Predictions for LHC energies provided

Inelastic screening effects are significant

Abstract

The experimental data on p, Lambda, Xi-, Omega-, baryons and the corresponding antibaryons spectra obtained by different collaborations are compared with the results of the calculations performed into the frame of the Quark-Gluon String Model. The contribution of String Junction diffusion and the inelastic screening corrections are accounted for in the theoretical calculations. The predictions of the Quark-Gluon String Model both for pp and pA collisions are extended up to the LHC energies.
