Abstract

We present results on two-particle azimuthal correlations with strange trigger particles (K0S, Λ, Ξ, Ω) associated with unidentified charged particles in d+Au and Au+Au collisions at . We investigate, in detail, the near-side associated yield as a function of centrality, pT and strangeness content in the trigger particle to look for possible flavour and baryon/meson differences. We compare our results to a fragmentation and recombination model, where the study of Ω-triggered correlations is used as a critical test of the validity of the recombination picture.
