Study of thermal properties of the medium produced in Au+Au collisions at sNN=7.7 GeV using a thermal model

In this study, we examine the thermal properties of the medium formed in ultra-relativistic heavy-ion collisions at chemical freeze-out using a thermal model. We utilize experimental data on various hadron species from 0% to 5% most central Au+Au collisions at [Formula: see text][Formula: see text]GeV from the STAR BES program to analyze the thermal properties, namely, chemical freeze-out temperature, baryon chemical potential, and strangeness chemical potential. We employ a [Formula: see text] minimization technique to obtain these thermal properties. Furthermore, we also obtain thermal properties with strangeness conservation condition and at zero potentials [Formula: see text]. We compare particle ratios from the thermal model with the experimental data. The thermal model describes particle ratios within [Formula: see text]2.5 standard deviations and [Formula: see text] between 1–2. We also discuss the collision energy dependence of thermodynamic properties of the medium at freeze-out and compare results with the published STAR results and other thermal model calculations.
