Strange and identified particle production with ALICE at the LHC

Abstract

The ALICE experiment has measured the production of strange and identified charged particles in pp, p–Pb and Pb–Pb collisions at LHC energies. Light-flavour hadrons are identified in various momentum ranges by using specific energy loss, timeof-flight, Cherenkov radiation, as well as decay topology and invariant mass analysis for weakly-decaying strange particles. In this contribution, the transverse momentum spectra at mid-rapidity and the corresponding yields measured in pp, p–Pb and Pb–Pb collisions for different multiplicity or centrality intervals are presented. The production of light-flavour hadrons in the three collision systems is compared and confronted with theoretical models.
