Abstract. EPOS generator allows one to simulate various types of collisions (nucleinuclei or even more complex ion-ion) with different initial parameters. It is based on Gribov-Regge theory. So far the EPOS model has been used to describe higher collision energies obtained with RHICbbRelativistic Heavy-Ion Collider or LHCccLarge Hadron Collider data. However, there is another program under investigation: Beam Energy Scan conducted at Brookhaven National Laboratory. The beams of gold ions are collided at energies such as sNN — 7.7; 11.5; 19.6, 27, 39, and 62.4 GeV in order to collect and analyze data needed to examine QGP Phase Diagram. The EPOS model could become a useful tool in such studies. Simulated with EPOS data will be verified using elliptic flow analyses and two-particles femtoscopic correlations, which allow one to measure the size of sources determined by newly created particle.
