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 textFormula: see textGeV 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 text2.5 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.
