Abstract

26 pages, 10 captioned figures, 3 tables, authors from page 21, figures at http://aliceinfo.cern.ch/ArtSubmission/node/3146 ; see paper for full list of authors ; In two-particle angular correlation measurements, jets give rise to a near-side peak, formed by particles associated to a higher $p_{\mathrm{T}}$ trigger particle. Measurements of these correlations as a function of pseudorapidity ($Δη$) and azimuthal ($Δφ$) differences are used to extract the centrality and $p_{\mathrm{T}}$ dependence of the shape of the near-side peak in the $p_{\mathrm{T}}$ range $1
