Particle Correlation Results from the ALICE Experiment at LHC

Measurements of two-particle correlations of inclusive and identified charged particles performed with the ALICE detector in Pb–Pb collisions at $\sqrt{s_{NN}}=2.76TeV$ are presented. The near-side jet shape is analyzed in the low $p_{\mathrm{T}}$ regions ($1<$p_{\rm T}$<8GeV\mathrm{/}c$). While the RMS of the peak in $\mathrm{\Delta }\phi$-direction is independent of centrality within uncertainties, we find significant broadening in $\mathrm{\Delta }\eta$-direction from peripheral to central collisions. The near-side $p\mathrm{/}\pi$ 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).
