Abstract

Full jet reconstruction in ALICE uses the combined information from charged and neutral par- ticles. Essentially all jet constituents can be measured with large efficiency down to very low transverse momenta (pT > 150 MeV/c). This has the advantage to introduce a minimum bias on the jet fragmentation, in particular for low jet momenta and in the presence of quenching. In this article, we present preliminary results from reconstruction of charged jets in Pb–Pb collisions at √sNN = 2.76 TeV. The inclusive charged jet spectrum, the jet nuclear modification factors (RAA, RCP), the ratio of spectra measured with different resolution parameters and hadron-jet correla- tions are discussed. For pp data at the same center of mass energy, the inclusive spectrum of fully reconstructed jets and its resolution parameter dependence are reported.
