Title: Multi-strange Particle Production In Relativistic Heavy Ion Collisions At √snn = 62.4 Gev
Author: Vasconcelos G.M.S.
Abstract: We present preliminary STAR results on measurements of multi-strange particles Ξ, Ω and their anti-particles from Au+Au and Cu+Cu at √sNN = 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, the Ω/φ ratio is shown for different systems and energies for a systematic study. © 2010 IOP Publishing Ltd.
