Measurement of light-flavour hadron production with ALICE in pp collisions at √s = 13 TeV — •Raul Tonatiuh Jimenez Bustamante for the ALICE collaboration — GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Germany — Physikalisches Institut, University of Heidelberg, Heidelberg, Germany

The ALICE detector has excellent Particle IDentification (PID) capabilities in the central barrel ( η < 0.9). This allows identified hadron production to be measured over a wide transverse momentum (p_T) range, using various sub-detectors and techniques: the particles’ specific energy loss (dE/dx), their velocity determination via time-of-flight measurement, their Cherenkov angle or their characteristic weak decay topology are exploited. Measurements of identified light-flavour hadron production at mid-rapidity with ALICE in proton-proton collisions at √s = 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 p_T range from 150 MeV/c up to 20 GeV/c, depending on the particle species.
