Abstract

We measure the relative abundances of strange mesons, baryons, and anti-baryons correlated with high-p_T trigger particles in ¹⁹⁷Au + ¹⁹⁷Au collisions at √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 Δϕ. 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.
