Energy and system dependence of high-$p_T$ triggered two-particle near-side correlations

Abstract

Previous studies have indicated that the near-side peak of high-pTp_T triggered correlations can be decomposed into two parts, the \textit{Jet} and the \textit{Ridge}. We present data on the yield per trigger of the \textit{Jet} and the \textit{Ridge} from d+Aud+Au, Cu+CuCu+Cu and Au+AuAu+Au collisions at sNN\sqrt{s_{NN}} = 62.4 GeV and 200 GeV and compare data on the \textit{Jet} to PYTHIA 8.1 simulations for p+pp+p. PYTHIA describes the \textit{Jet} component up to a scaling factor, meaning that PYTHIA can provide a better understanding of the \textit{Ridge} by giving insight into the effects of the kinematic cuts. We present collision energy and system dependence of the \textit{Ridge} yield, which should help distinguish models for the production mechanism of the \textit{Ridge}.
