dc.descriptionInformation about the space-time evolution of colliding nuclei can be extracted correlating particles emitted from nuclear collisions. The high density of particles produced in the STAR experiment allows the measurement of non-identical strange particle correlations. Due to the absence of Coulomb interaction, $p-Λ$ and $\bar{p}-Λ$ systems are more sensitive to the source size than $p-p$ pairs. Strong interaction potential has been studied using $p-Λ$, and for the first time, $\bar{p}-Λ$ pairs. The experimental correlation functions have been described in the frame of a model based on the $p-n$ interaction. The first preliminary measurement of $π$ - $Ξ$ correlations has been performed, allowing to extract information about the freeze-out time and the space-time asymmetries in particle emission closely related to the transverse radial expansion and decay of resonances.
