Abstract

ALICE is the LHC experiment dedicated to the study of Heavy-Ion collisions. Many observables related to the properties of the medium created in such collisions rely on the excellent capabilities of the detector in terms of Particle Identification (PID) of particles. In the following, the various PID techniques used for the different ALICE analyses will be described. Focus will be given to the detectors' performance, and selected results will be presented on pp data collected at sqrt(s) = 7 TeV and PbPb collisions at sqrt(s_NN) = 2.76 TeV.
