Strange hadron yields and ratios in heavy ion collisions at RHIC energy

TL;DR

This paper examines the robustness of the quark coalescence model in describing strange hadron production in heavy ion collisions at RHIC, considering different wave-function overlaps to test its reliability.

Contribution

It introduces a study of the impact of various wave-function overlaps on the coalescence model's predictions for hadron yields at RHIC.

Findings

Coalescence model successfully reproduces experimental data.

Wave-function overlap variations affect hadron yield predictions.

Robustness of the coalescence description is evaluated.

Abstract

Recent experimental data support the presence of quark coalescence in heavy ion collisions at RHIC energies. Hadronization of quark matter and hadron formation in heavy ion collisions can be described by the coalescence process, and measured data are reproduced successfully. On the other hand, the theoretical coalescence calculations are based on a non-relativistic description. Here we investigate the robustness of the coalescence description, using different wave-function overlap during hadron formation.
