Description
Femtoscopic techniques provide a direct tool to measure the space--time extent and dynamical evolution of the system created in heavy-ion collisions. Identical pion pairs have conventionally been used for source size measurements because of their large production yields and well-understood interactions. In addition to determining the source dimensions, femtoscopic analyses offer a powerful approach to investigate the final-state interactions among different particle species, including both strong and Coulomb interactions.
In this talk, we will present a review of recent femtoscopic measurements performed by the STAR experiment at RHIC. The review will cover recent results on pion, kaon, proton, strange-baryon, and light-nuclei femtoscopy. The results include correlations of both identical and non-identical pairs of mesons and baryons, which arise from quantum statistics and final-state interactions and provide unique information on the space--time characteristics of particle production. Particular emphasis will be given to recent measurements from the Beam Energy Scan-II (BES-II) program, including both fixed-target and collider-mode operations, as well as from Au+Au and isobar (Ru+Ru and Zr+Zr) collisions at $\sqrt{s_{NN}}$ = 200 GeV.
