Jet-like near-side peak shapes in Pb–Pb collisions at image with ALICE

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 image. 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 image (image). We observe that the rms in Δη increases with the centrality of the collisions whereas the rms in Δϕ stays constant within experimental uncertainties.
