Pentaquark Search in Relativistic Heavy Ion Collisions with STAR

Abstract

We report on the progress of the pentaquark searches by the STAR collaboration in p+p, d+Au, and Au+Au at $s_{NN}=\sqrt{200}$ GeV collisions through one of the decay modes of $\Theta^{+}\to p+K_{s}^{0}$. $\Theta^{+}$ state is an exotic baryon with strangeness S=1 and is the lightest isospin member of the expected antidecuplet. We compare our techniques for the pentaquark search with those for the short-lived resonances. These results were presented as a poster at Quark Matter 2004.
