Probing Hydrodynamics at √ s_NN = 7.7 GeV: Model Comparisons of the Bulk Properties of Au + Au Collisions

We study hydrodynamic effects of bulk properties of the matter produced in Au + Au collisions at √ s_NN = 7.7 GeV measuring production of the following particles π ± , K± , p and p̄ with AMPT, EPOS4, SMASH, and PYTHIA8 Monte Carlo models. Mid-rapidity ( | y | < 0.1 ) analysis of the transverse momentum spectra, antiparticle-to-particle and mixed-particles ratios, in dependence of various collision centralities are presented and compared with the 2010 data collected by STAR experiment in the Beam Energy Scan (BES) program at the Relativistic Heavy Ion Collider (RHIC).
