AbstractWe measure relative abundances of K(S)(0), Lambda and (Lambda) over bar in near-sideand away-side cones correlated with triggered high-p(T) particles in (197)Au + (197)Au collisions at root(S)NN = 200 GeV. The centrality dependence of identified particles in the triggered particle cones is also presented. Particle yields and ratios are extracted on the near side and away side of the trigger particle. The associate-particle ratios are studied as a function of the angle relative to the trigger particle azimuth Delta phi. Such studies should help elucidate the origin of the modifications in the jet-like correlations observed in Au+Au collisions relative to p+p collisions. And these studies will also help us in understanding the variation of local parton densities at the away side. We discuss how these measurements might be related to several scenarios for interactions of fast partons with the medium created in Au+Au collision.
