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

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, Volume 720, No. 1-3, Year 2013

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=2.76 TeV with ALICE at the LHC. The data are presented in the pT range 0.1530 GeV/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. © 2013 CERN
