EPOS is a generator which allows one to simulate various types of collisions of divers systems with different initial parameters. It considers the parton-based Gribov-Regge theory. So far the EPOS model has been used to describe higher collision energies obtained with RHIC or LHC data. On the other hand, 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 in examination of 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.
