System size dependence of strange particle correlations in Cu plus Cu and Au plus Au collisions at root s(NN)=200GeV in STAR at RHIC

摘要

Two-particle azimuthal correlations with strange trigger particles (K-S(0), Lambda, Xi) are presented in Cu+Cu and Au+Au collisions at root s(NN) = 200 GeV in STAR at RHIC. The near-side associated yield is investigated as a function of centrality, p(T), and strangeness content of the trigger to investigate possible flavour or meson/baryon differences. The system size dependence of both the jet-like correlations and the long-range pseudorapidity correlations is studied to give insight into the origin of these two components.
