Measurements of two-particle correlations of inclusive and identified charged particles performed with the ALICE detector in Pb--Pb collisions at √sNN = 2.76 TeV are presented. The near-side jet shape is analyzed in the low p\rm T regions (1<p\rm T<8GeV/c). While the RMS of the peak in Δφ-direction is independent of centrality within uncertainties, we find significant broadening in Δη-direction from peripheral to central collisions. The near-side p/π ratio of particles associated to a trigger particle from jet fragmentation in the central Pb--Pb collisions is consistent with vacuum fragmentation in the measured momentum region (1.5<p\rm T<4.5GeV\c).
