Paper Abstract

Geometry and dynamics of the source produced as a results of heavy-ion collisions at high energies can be studies via femtoscopy method. Correlations of two particles at small relative momentum are sensitive to the effects of Quantum Statistics and the Final State Interactions. They allow one to study the space-time properties of the source which are of the order of 1015 m and 10−23 s, respectively. Beam Energy Scan (BES) program conducted at the Relativistic Heavy Ion Collider (RHIC) covers an important part of the QCD Phase Diagram with beams of Au ions accelerated to relativistic velocities. Already completed first phase of the BES program uses heavy-ions collided in the energy range measured in the reference frame of center of mass from 7.7 to 200 GeV. This is a baryon-rich region that can be studied via femtoscopy methods with baryons. On one hand meson-meson correlations are the most commonly studied and baryon-baryon systems together with two-meson and meson-baryon correlations provide a complete information about source parameters. On the other hand the measurements of non-identical particle combinations complement our knowledge about space-time asymmetries during emission process. Physics of heavy-ion collisions is successfully deduced basing on studies of the properties of the particle-emitting source and how they change with different collision energies. Such studies include various centralities of the collision. In this paper, the STAR preliminary results including femtoscopic systems of various particle combinations such as protons, pions and kaons produced as a results of Au+Au collisions at BES energies are discussed.
