We measure relative abundances of $K_{S}^{0}$, $Lambda$ and $bar{Lambda}$ in near-side and away-side cones correlated with triggered high-$p_{T}$ particles in $^{197}$Au + $^{197}$Au collisions at $sqrt{s_{NN}}$ = 200 GeV. The centrality dependence o
f 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 $Deltaphi$. 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 also will help understand 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.
We measure the relative abundances of strange mesons, baryons, and anti-baryons correlated with high-$p_T$ trigger particles in $^{197}$Au + $^{197}$Au collisions at $sqrt{s_{NN}}$ = 200 GeV. 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 $Deltaphi$. Such studies should help elucidate the origin of the previously observed correlations and their strong modifications in Au+Au collisions relative to p+p collisions. We discuss how these measurements might be related to several scenarios for interactions of fast partons with the medium in Au+Au collision.
