The ALICE experiment collected collisions at LHC at √s = 0.9TeV and √s = 7.0TeV with proton-proton and at √sNN = 2.76TeV with lead-lead. ALICE, compared with other LHC experiments, has several detectors with Particle
IDentification (PID) capabilities. Physics results involving PID will be presented, with special emphasis on the Time-Of-Flight (TOF) analysis
