Production of pions, kaons and protons at high pT in sqrt{s_NN}=2.76 TeV Pb-Pb collisions

In this work we report on the production of charged pions, kaons, and (anti) protons in pp and Pb-Pb collisions at sqrt{s_NN}= 2.76 TeV for 3 < pT < 20 GeV/c. The evolution of the nuclear modification factor, RAA, with collision centrality and transverse momentum is discussed.In this work we report on the production of charged pions, kaons, and (anti) protons in pp and Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76TeV for 3<p_T<20GeV/c. The evolution of the nuclear modification factor, R_A_A, with collision centrality and transverse momentum is discussed.In this work we report on the production of charged pions, kaons, and (anti) protons in pp and Pb-Pb collisions at sqrt{s_NN}= 2.76 TeV for 3 < pT < 20 GeV/c.
