Production of identified hadrons in Au+Au collisions at √s_NN = 54.4 GeV at RHIC

Quantum chromodynamics (QCD) predicts that at sufficiently high temperature (T) and/or the baryon chemical potential (µ_B), a deconfined state of quarks and gluons, known as the quark–gluon plasma (QGP), is formed. Understanding the QCD phase diagram is one of the primary goals of high-energy heavy ion collision experiments. The study of spectra of identified hadrons provides crucial information about the equilibrium dynamics as well as the bulk properties of the system produced in heavy-ion collisions. We present the transverse momentum spectra for π ±, K^±, and p(p¯) in Au+Au collisions at √s_NN = 54.4 GeV. The particle ratios from Au+Au collisions at √s_NN = 54.4 GeV follow the trend shown from previous measurements of AGS, SPS, RHIC, and LHC. The kinetic freeze-out temperature and transverse radial flow velocity show an anticorrelation
