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 RHIC b or LHC c 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 √ s 11.5, 19.6, 27, 39, and 62.4

... 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. EPOS Energy conserving quantum mechanical multiple scattering approach, based on Partons (parton ladders), Off-shell remnants, and Splitting of parton ladders [1]. a
