Jet-like near-side peak shapes in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV with ALICE

We present preliminary results from di-hadron correlations in azimuth (phi) and pseudo-rapidity (eta) induced by hadronic di-jets produced in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV. The jet-like near-side peak has been isolated from eta-independent collective flow correlations using an eta-gap method and its shape has been characterized by rms and excess kurtosis. These quantities have been studied as a function of centrality as well as of trigger (associated) particle transverse momentum ranging from 2-8 GeV (1-3 GeV). We observe that the rms in Deta increases with the centrality of the collisions whereas the rms in Dphi stays constant within experimental uncertainties.We present preliminary results from di-hadron correlations in azimuth ( ϕ ) and pseudo-rapidity ( η ) induced by hadronic di-jets produced in Pb–Pb collisions at sNN=2.76TeV . The jet-like near-side peak has been isolated from η -independent collective flow correlations using a η -gap method and its shape has been characterized by rms and excess kurtosis. These quantities have been studied as a function of centrality as well as of trigger (associated) particle transverse momentum ranging from 2 – 8GeV/c ( 1 – 3GeV/c ). We observe that the rms in Δ η increases with the centrality of the collisions whereas the rms in Δ ϕ stays constant within experimental uncertainties.We present preliminary results from di-hadron correlations in azimuth (phi) and pseudo-rapidity (eta) induced by hadronic di-jets produced in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV.
