【 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 velocity determination via time-of-flight measurement, the Cherenkov angle or their characteristic weak decay topology. Results on identified light flavour hadron production at mid-rapidity measured by ALICE in proton-proton collisions at = 13 TeV are presented and compared with previous measurements performed at lower energies. The results cover a wide range of particle species including long-lived hadrons, resonances and multi-strange baryons over the pTrange from 150 MeV/c up to 20 GeV/c, depending on the particle species.
