【 摘 要 】

An overview of recent results on jet physics from the ALICE collaboration is presented. We mainly discuss azimuthal correlations and nuclear modification factors for both hadrons and jets. The very low pTtracking (> 150 MeV/c) capabilities of the ALICE detector associated to its electromagnetic calorimetry, allow to reconstruct both charged jets and full jets, with minimum bias on the jet fragmentation. A detailed measurement of the underlying event fluctuations will be discussed, as well as, jet spectra measurements, in pp and Pb-Pb collisions, using low constituent pTcuts and hadron-recoil jet correlations, which give a controlled way to subtract the combinatorial background.
