| Summary: | We report results on jet production in Pb–Pb collisions at √sNN = 2.76 TeV from the ALICE collaboration. The nuclear modification factor of jets reconstructed with a resolution parameter R=0.2 shows a strong, centrality dependent suppression with respect to pp collisions. The azimuthal anisotropy of charged jet production relative to the event plane is studied. In semi-peripheral events, a significant υ2ch jet is observed, indicating path-length dependent in-medium parton energy loss. The measurement of jet shapes allows characterizing the intra-jet momentum flow of quenched jets. The measured radial moment and dispersion of the constituent transverse momentum distribution indicate a collimation and hardening of the jet core in Pb–Pb relative to pp collisions. |
