Abstract

The space-time evolution of the source of particles formed in the collision of nuclei can be studied through particle correlations. The STAR experiment is dedicated to study ultra-relativistic heavy ions collisions and allows to measure non-identical strange particle correlations. The source size can be extracted by studying pΛp-\Lambda, pˉΛˉ\bar{p}-\bar{\Lambda}, pˉΛ\bar{p}-\Lambda and pΛˉp-\bar{\Lambda} correlation functions. Strong interaction potential has been studied for these systems using an analytical model. Final State Interaction (FSI) parameters have been determined and has shown a significant annihilation process present in pˉΛ\bar{p}-\Lambda and pΛˉp-\bar{\Lambda} systems not present in pΛp-\Lambda and pˉΛˉ\bar{p}-\bar{\Lambda}.
