摘      要：The jet radial structure and particle transverse momentum (pT) composition within jets are presented in centrality-selected Pb–Pb collisions at √sNN = 2.76 TeV. Track-based jets, which are also called charged jets, were reconstructed with a resolution parameter of R = 0.3 at midrapidity |ηchjet| T,chjet = 30–120 GeV/c. Jet–hadron correlations in relative azimuth and pseudorapidity space (∆, ∆η) are measured to study the distribution of the associated particles around the jet axis for different pT,assocranges between 1 and 20 GeV/c. The data in Pb–Pb collisions are compared to reference distributions for pp collisions, obtained using embedded PYTHIA simulations. The number of high-pT associate particles (4 T,assoc T associate particles are slightly more collimated in Pb–Pb collisions compared to the reference, while low-pT associate particle tend to be broadened. The results, which are presented for the first time down to pT,chjet = 30 GeV/c in Pb–Pb collisions, are compatible with both previous jet–hadron-related measurements from the CMS Collaboration and jet shape measurements from the ALICE Collaboration at higher pT, and add further support for the established picture of in-medium parton energy loss.
