High-pT strange particle spectra and correlations in STAR

Abstract

We present results on strange particle production in p+p, d+Au and Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. We discuss the nuclear modification factors ($R_{CP}$) and ratios of particle yields in order to investigate the range of anomalous baryon production.The medium modification of the fragmentation process is further explored by studying azimuthal correlations at intermediate-$p_T$ for $K_S^0$, $\Lambda$ and $\bar{\Lambda }$ trigger particles. The results are compared to fragmentation and recombination models.
