${\Xi }^{-}$ and ${\bar{\Xi }}^{+}$ baryon production in Au+Au collisions at $\sqrt{s_{NN}}=130$ GeV

Abstract

We report preliminary results on the centrality dependence of the ${\Xi }^{-}$ and ${\bar{\Xi }}^{+}$ production at mid-rapidity in $\sqrt{s_{NN}}=130$ GeV Au+Au collisions from the STAR experiment. For the most central data the obtained yields suggest a saturation of strangeness production per produced hadron. The calculated inverse slope parameter may indicate an earlier freeze-out of these particles.
