System and energy dependence of strange and non-strange particle correlations in STAR at RHIC

Abstract

Two-particle high-$p_T$ triggered correlations in $Cu+Cu$ and $Au+Au$ collisions at $\sqrt{s_{NN}}$ = 62 $GeV$ and $\sqrt{s_{NN}}$ = 200 $GeV$ in STAR at RHIC are presented. The $N_{part}$, $p_T^{associated}$, and $p_T^{trigger}$ dependence of the yield per trigger in the \textit{Jet} and \textit{Ridge} components of the near-side is investigated for h, $K^0_S$, $\Lambda$, and $\Xi$ trigger and associated particles. The system and energy dependence of these components is a potentially powerful tool to distinguish between models used to describe their production.
