Abstract
We report a measurement of transverse momentum spectra of jets detected with the ALICE detector in Pb-Pb collisions at √sNN=2.76 TeV. Jets are reconstructed from charged particles using the anti-kT jet algorithm. 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 R = 0.2 and R = 0.3 for different centrality classes and compare the jet yield in Pb–Pb and pp events.
