Description
Geometry and dynamics of the particle-emitting source in heavy-ion collisions can be inferred via femtoscopy method. Two-particle correlations at small relative momentum exploit Quantum Statistics (QS) and the Final State Interactions (FSI) which allow one to study the space-time characteristics of the source of the order of 10^{−15} m and 10^{−23} s. The RHIC Beam Energy Scan (BES) program covers significant part of the QCD Phase Diagram using collisions of Au nuclei for several beam energies from 7.7 to 200 GeV, which baryon-rich region is studied via femtoscopy. Baryon measurements together with meson ones provide complementary information about source characteristics.
In this talk, results on femtoscopic measurements of various particle combinations at different collision energies and centralities will be shown. The results of non-identical particles enables studies of space-time asymmetries in emission process. In addition, femtoscopy enables investigation of FSI between hadrons.
