pi+Xi- Correlations and the $Ξ^{*}(1530)$ Puzzle

Abstract

The analysis of the preliminary RHIC data on $π^{+}-Ξ^{-}$ correlation function is carried out.The $Ξ^*(1530)$ resonance is successfully described. The values of the fireball radius and of the $π^{+}-Ξ^{-}$ scattering lengths are obtained.
