Strange particles production in relativistic nucleus-nucleus collisions at the RHIC BES energy region

TL;DR

This paper uses the PACIAE model to analyze strange particle production in gold-gold collisions at various energies, successfully matching experimental data from the RHIC Beam Energy Scan.

Contribution

It demonstrates the effectiveness of the PACIAE model in reproducing strange particle transverse momentum distributions across different energies and centralities.

Findings

PACIAE model fits experimental transverse momentum distributions well

Strange particle production varies with collision energy and centrality

Model results align with RHIC BES experimental data

Abstract

The parton and hadron cascade model PACIAE is used to investigate strange particle production in Au + Au collisions at GeV in different centralities and at 39, 11.5 and 7.7 GeV in the most central collision, respectively. It is shown that the transverse momentum distributions of strange particles by the PACIAE model fit the RHIC Beam Energy Scan experimental results well.
