Centrality dependence of multistrange baryon production in high-energy heavy-ion collisions

TL;DR

This paper analyzes how the production of multistrange baryons and antibaryons varies with collision centrality in high-energy heavy-ion collisions across SPS to LHC energies, using the Quark-Gluon String Model.

Contribution

It demonstrates the centrality dependence of strange baryon ratios in heavy-ion collisions within the Quark-Gluon String Model framework.

Findings

Significant centrality dependence of antibaryon ratios at SPS energies.

Analysis spans from SPS to LHC energy regions.

Supports the role of collision centrality in strange baryon production.

Abstract

We consider the experimental data on the production of strange Lambdas, and multistrange baryons (Xi, Omega), and antibaryons, on nuclear targets, at the energy region from SPS up to LHC, in the framework of the Quark-Gluon String Model. One remarkable result of this analysis is the significant dependence on the centrality of the collision of the experimental ratios bar(Xi)+/bar(Lambda) and bar(Omega)+/bar(Lambda) ratios in heavy-ion collisions, at SPS energies.
