Baryon-Strangeness correlations in Parton/Hadron transport model for Au + Au collisions at \sqrt{s_{NN}} = 200 GeV

TL;DR

This study uses a multi-phase transport model to analyze baryon-strangeness correlations in gold-gold collisions at high energy, revealing how hadronization and rescattering affect observable signatures.

Contribution

It demonstrates how baryon-strangeness correlation signatures evolve through different collision phases, highlighting the impact of hadronization and rescattering.

Findings

Partial C$_{BS}$ signatures survive after parton coalescence.

Hadronic rescattering completely erases C$_{BS}$ signatures.

Centrality influences the evolution of C$_{BS}$ in the collision.

Abstract

Baryon-strangeness correlation (C$_{BS}$) has been investigated with a multi-phase transport model (AMPT) in $^{197}$Au + $^{197}$Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The centrality dependence of C$_{BS}$ is presented within the model, from partonic phase to hadronic matter. We find that the system still reserve partial predicted signatures of C$_{BS}$ after parton coalescence. But after hadronic rescattering, the predicted signatures will be obliterated completely. So it seems that both coalescence hadronization process and hadronic rescattering are responsible for the disappearance of the C$_{BS}$ signatures.
