Abstract

Light flavour transverse momentum spectra at intermediate and high pT provide\nan important baseline for the measurement of perturbative QCD processes in pp,\nfor the evaluation of initial state effects in p-Pb, and for investigating the\nsuppression from parton energy loss in Pb-Pb collisions. The measurement of the\nnuclear modification factor RpPb for inclusive charged particles is extended up\nto 50 GeV/c in pT compared to our previous measurement and remains consistent\nwith unity up the largest momenta. Results on RpPb of charged pions, kaons and\nprotons that cover up to 14 GeV/c in pT are presented and compared to RpPb of\ninclusive charged particles. On the production of charged pions, kaons, and\nprotons up to pT = 20 GeV/c in Pb-Pb collisions final results for RAA are\npresented.\n
