Multi-strange particle production in relativistic heavy ion collisions at \(\sqrt{s_{NN}}=62.4\) GeV

We present preliminary STAR results on measurements of multi-strange particles \(\Xi\), \(\Omega\) and their anti-particles from Au+Au and Cu+Cu at \(\sqrt{s_{NN}}=62.4\) GeV collisions. In order to better understand the role of strangeness enhancement in nucleus-nucleus collisions and its scaling p...

Description
Summary:We present preliminary STAR results on measurements of multi-strange particles \(\Xi\), \(\Omega\) and their anti-particles from Au+Au and Cu+Cu at \(\sqrt{s_{NN}}=62.4\) GeV collisions. In order to better understand the role of strangeness enhancement in nucleus-nucleus collisions and its scaling properties with system size, we compare the results from Au+Au and Cu+Cu reactions for different event centrality classes. Strangeness enhancement is discussed in the context of multi-strange to pion ratios. Finally, \(\Omega/\phi\) ratio is shown for different systems and energies for a systematic study.
