High-pT azimuthal correlations of neutral strange baryons and mesons in STAR at RHIC
Jana Bielcikova
Abstract
We present results on two-particle azimuthal correlations of high-pT neutral strange baryons (Λ,Λ) and mesons (K0S) associated with non-identified charged particles in d+Au and Au+Au collisions at sNN = 200 GeV. In particular, we discuss properties of the near-side yield of associated charged particles as a function of centrality, transverse momentum and zT, as well as possible baryon/meson and particle/antiparticle differences. The results are compared to the proton and pion triggered correlations and to fragmentation and recombination models.
