Abstract

Properties of nuclear matter under extreme conditions can be studied through experiments with heavy-ion collisions at high energy. It is not possible to directly measure the sizes of particle-emitting sources, but it is possible to infer them with the use of femtoscopy. In order to determine the space-time properties of the sources, the femtoscopy uses Quantum Statistics effects and Final State Interactions. Radii of the sources can be obtained from various particle types and the comparison of those should provide a complementary information about the source. In this report we present preliminary results of proton and antiproton femtoscopic correlations in Au+Au collisions at √sNN of 7.7 GeV, 11.5 GeV and 39 GeV measured in STAR.
