Light and strange hadron production and anisotropic flow measurement in Au+Au collisions at ${\sqrt{s_{\rm NN}} = \rm{3\,GeV}}$ from STAR

TL;DR

This paper reports the first measurements of identified particle production and anisotropic flow in 3 GeV Au+Au collisions, revealing significant differences in the produced matter compared to higher energies.

Contribution

It provides new experimental data on particle production and flow at 3 GeV, and compares these results with theoretical models to understand the matter properties.

Findings

Produced matter at 3 GeV differs from higher energy collisions.

Thermal and transport models are compared to experimental data.

Results suggest different physical conditions at this energy.

Abstract

In this proceeding, we present on our first measurements of identified particle ($\pi$, $K$, $p$, $K_{s}^{0}$, $\Lambda$, $\phi$, $\Xi^{-}$) production and anisotropic flow ($v_{1}$, $v_{2}$) in Au+Au collisions at ${\sqrt{s_{\rm NN}} = \rm{3\,GeV}}$. Various models including thermal and transport model calculations are compared to data, these results imply that the matter produced in the 3 GeV Au+Au collisions is considerably different from that at higher energies.
