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 $p-\Lambda$, $\bar{p}-\bar{\Lambda }$, $\bar{p}-\Lambda$ and $p-\bar{\Lambda }$ 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 $\bar{p}-\Lambda$ and $p-\bar{\Lambda }$ systems not present in $p-\Lambda$ and $\bar{p}-\bar{\Lambda }$.
