Popis: | International audience; In these proceedings, we report the ALICE measurements of inclusive charged jet production in pp and Pb-Pb collisions at the currently highest available centre-of-mass energy at the LHC of 5.02 TeV. Charged jet spectra are extracted after jet-area based soft background subtraction and unfolding. Charged jet production cross sections as well as nuclear modification factors ($R_{AA}$) are presented. Furthermore, the inclusive charged jet production cross section in pp collisions is compared to QCD calculations. Our $R_{AA}$ results show a significant jet suppression in the most central Pb-Pb collisions at 5.02 TeV. A comparison to $R_{AA}$ measurements obtained at lower centre-of-mass energy is also presented. |
