Sumario: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 at = 2.76 TeV. We observe significant broadening of the jet-like peak that increases with decreasing ptrigT and passocT and with increasing centrality and additional broadening of the jet-like peak in Δη with respect to broadening in Δ in most central collisions.The prospects of expanding these studies to include strange particles (Λ, and K0S) is explored.
