【 摘 要 】

The ALICE detector has excellent Particle IDentification (PID) capabilities in the central barrel (|η| T) range, using different sub-detectors and techniques: their specific energy loss (dE/dx), the time of flight, the Cherenkov angle or their characteristic weak decay topology. Results on identified particle spectra and production yield ratios at mid-rapidity measured by ALICE in different colliding systems (pp, p-Pb and Pb-Pb) are presented and the similarities among them are discussed. For Pb-Pb collisions the nuclear modification factor as a function of pTis shown for different collision centralities.
