Centrality dependence of charged particle production at large transverse momentum in Pb-Pb collisions at sNN=2.76TeV

The inclusive transverse momentum (pT) distributions of primary charged particles are measured in the pseudo-rapidity range |η|<0.8 as a function of event centrality in Pb-Pb collisions at sNN=2.76TeV with ALICE at the LHC. The data are presented in the pT range 0.1530GeV/c. In peripheral collisions (70-80%), only moderate suppression (RAA=0.6-0.7) and a weak pT dependence is observed. The measured nuclear modification factors are compared to other measurements and model calculations.
