# Proton - Lambda correlations in Au-Au Collisions at $\sqrt{s_{NN}} = 200$ GeV from the STAR experiment

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 p–Λ, $\overline{\rm p}$–$\overline{\Lambda}$, $\overline{\rm p}$–$\Lambda$ and p–$\overline{\Lambda}$ 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 $\overline{\rm p}$–$\Lambda$ and p–$\overline{\Lambda}$ systems not present in p–$\Lambda$ and $\overline{\rm p}$–$\overline{\Lambda}$.
