Adaptation of the THERMINATOR model for the BES program

THERMINATOR model is a Monte Carlo event generator invented to study the statistical production of particles created in relativistic heavy-ion collisions. Its current description allows one to study the highest collision energies achieved by LHC and RHIC colliders. However it is possible to adapt THERMINATOR model to the lower
energy spectrum as is used in Beam Energy Scan (BES) program at RHIC. Femtoscopy of two particles investigates the properties of matter produced in heavy-ion collisions. Two-particle correlations use Quantum Statistics and the Final State Interactions which allow one to examine the space-time characteristics of the medium. For the first time we present single- and two-particle momentum distributions of identified particles generated for the energy spectrum from BES program. To verify how model predictions agree with experimental results, we compare transverse momentum distributions of pions, kaons and protons and the correlation functions obtained for identical pions in Au+Au collisions to the results from the STAR experiment from BES program.
