Abstract
The identified charged hadron ( \(\pi^{\pm}\) , \(K^{\pm}\) , \(p\) , \(\bar{p}\) ) invariant spectra obtained using hydrodynamic version of UrQMD model simulations in different centrality classes of Bi \(+\) Bi collisions at the energy of \(\sqrt{s_{NN}}=9.2\) GeV are presented. The spectra are analyzed using the Blast-Wave relativistic hydrodynamics model to extract the kinetic freeze-out temperature and average radial flow velocity. In addition, the ratios of antiproton to proton yields are used to estimate the baryon chemical potential. The study focuses on developing a methodology to extract thermodynamic parameters from identified hadron spectra, which is important for assessing the sensitivity of the MPD experiment at NICA to measurements of freeze-out and phase transition conditions. The applicability of the proposed approach for future experimental data and its relevance for exploring the nuclear matter phase diagram are also discussed.
