Description

Exploring the QCD phase diagram and searching for the QCD critical point are some of the main goals of the Beam Energy Scan program at RHIC. In 2017, the STAR experiment collected large dataset of Au+Au collisions at $\sqrt{s_{NN}}=$ 54.4 GeV. The identified particle spectra and yields provide information about the bulk properties of the hot medium created in these collisions. The centrality dependence of the freeze-out parameters explores a wide ($T$, ${\mu }_B$) region in the phase diagram facilitating the search for the QCD critical point.

We present the measurements of the production of ${\pi }^{\pm }$, K${}^{\pm }$, p, and $\overline{p}$ at midrapidity $|y|\le 0.1$. The results for the transverse momentum spectra, particle yields dN/dy, average transverse momentum $⟨$p${}_T$$⟩$, and particle ratios will be presented for different centrality classes and compared with AMPT and HIJING model calculations. In addition, the extracted freeze-out parameters will be compared with the results at other collision energies. The physics implications of the results will be discussed.
