【 摘 要 】

Two-particle angular correlations provide a powerful tool to study jets and their modification in ultra-relativistic heavy-ion collisions. The study of the particle species dependence of correlation structures as a function of transverse momentum provides additional information on particle production mechanisms. In this contribution we present studies of a near-side jet-like correlation peak in h-h correlations in Pb{Pb collisions atSNN = 2:76 TeV. We observe significant broadening of the jet-like peak that increases with decreasing ptrig T and passoc T and with increasing centrality and additional broadening of the jet-like peak in with respect to broadening in δ in most central collisions. The prospects of expanding these studies to include strange particles (A, A and K0S) is explored.
