Abstract

We present transverse momentum distributions of inclusive charged particles and identified hadrons in pppp and Pb--Pb collisions at \rs=2.76\rs= 2.76 TeV, measured by ALICE at the LHC. The Pb--Pb data are presented in intervals of collision centrality and cover transverse momenta up to 50 GeV/cc. Nuclear medium effects are studied in terms of the nuclear modification factor \raa. The results indicate a strong suppression of high-pTp_T particles in Pb--Pb collisions, consistent with a large energy loss of hard-scattered partons in the hot, dense and long-lived medium created at the LHC. We compare the preliminary results for inclusive charged particles to previous results from RHIC and calculations from energy loss models. Furthermore, we compare the nuclear modification factors of inclusive charged particles to those of identified π0\pi^0, π±\pi^{\pm}, Ks0^0_s, and Λ\Lambda.
