Hadron Correlations Measured with ALICE
Abstract
Angular particle correlations are a powerful tool to study collective effects and in-medium jet modification as well as their interplay in the hot and dense medium produced in central heavy-ion collisions. We present measurements of two-particle angular correlations of inclusive charged and identified particles performed with the ALICE detector. The near-side peak in the short-range correlation region is quantitatively analyzed: while the rms of the peak in -direction is independent of centrality within uncertainties, we find a significant broadening in -direction from peripheral to central collisions. The particle content of the near-side peak is studied finding that the ratio of particles associated to a trigger particle is much smaller than the one in the bulk of the particles and consistent with fragmentation of a parton in vacuum.
