Strangeness Production in Heavy-Ion Collisions at STAR

Abstract

We report an overview of strangeness production in Cu+Cu and Au+Au collisions at the energies $\sqrt{s_{NN}}=$ 62.4 and 200 GeV. We show new mid-rapidly $dN/dy$ results for the $K_S^0$, $\Lambda$, $\Xi$, $\Omega$ particles in Cu+Cu \sNN{62} collisions and compare to results in Au+Au \sNN{62} collisions. We show new results for mid-$p_T$ $\Lambda /K_S^0$ ratios in Cu+Cu \sNN{62} collisions and again compare to ratios in Au+Au \sNN{62} collisions. Finally, we show the high-$p_T$ ($\sim 6.2$ GeV/c) $R_{AA}(K_S^0)$ as a function of system size in Au+Au \sNN{200} collisions and compare to $R_{AA}(\pi )$.
