Description

We report a measurement of transverse momentum spectra of jets detected with the ALICE detector in Pb-Pb collisions at $\sqrt{s_NN}$=2.76 TeV. Jets are reconstructed from charged particles using the anti-$k_{T}$ jet algorithm. The transverse momentum of tracks is measured down to 150 MeV/c which gives access to the low $p_{T}$ fragments of the jet. The background from soft particle production is determined for each event and subtracted. The remaining influence of underlying event fluctuations is quantified by embedding different probes into heavy-ion data. The reconstructed transverse momentum spectrum is corrected for background fluctuations by unfolding. We compare the inclusive jet spectra reconstructed with radii between 0.2 and 0.4 for different centrality classes and compare the jet yield in Pb-Pb and pp events.
