Description

Thanks to its unique particle identification capabilities the ALICE detec- tor is able to identify light fl vour, resonances, strange and multi-strange hadrons, including π, K, p, K0 , Λ, Ξ, Ω, ρ(770), φ(1020), over a wide range of transverse momentum, from pp and p-Pb interactions up to central Pb–Pb collisions. The latest results on transverse momentum spectra and the nu- clear modifi factor, RAA, as a function of the Pb–Pb collision centrality will be presented for various particle species at 2.76 TeV center of mass en- ergy. The RAA will be compared with the nuclear modifi factors in p-Pb collisions, to discuss the presence of hot nuclear matter effects affecting the high-pT particle production in Pb–Pb collisions. The results on the RAA of charged hadrons at √sNN = 5.02 TeV, the highest energy ever reached in the laboratory for heavy-ion collisions, will also be presented.
