Abstract

Measurements of jet yields in heavy-ion collisions can be used to constrain jet energy loss models, and in turn provide information about the physical properties of deconfined QCD matter. ALICE reconstructs charged particle jets (charged jets\textit{charged jets}) with high-precision tracking of charged particles down to pTtrack=150p_{\mathrm{T}}^{\mathrm{track}} = 150 MeV/cc, and jets (full jets\textit{full jets}) with the addition of particle information from the electromagnetic calorimeter down to Ecluster=300E_{\mathrm{cluster}} = 300 MeV. By including low momentum jet constituents, ALICE is uniquely positioned at the LHC to measure jets down to low jet momentum, to determine the modification to the soft components of jets, and to measure medium recoil particles. New inclusive full jet measurements in pp and Pb-Pb collisions at sNN=5.02\sqrt{s_{\mathrm{NN}}}=5.02 TeV with ALICE will be shown, over R=0.20.4R=0.2-0.4 and extending to low jet pTp_{\mathrm{T}}. These will include the jet RAAR_{\mathrm{AA}} for different jet RR, and will constitute the first such full jet measurements at low transverse jet momentum at this collision energy. The results are compared to several theoretical predictions.
