Abstract
The inclusive transverse momentum (pT) distributions of primary charged particles are measured in the pseudo-rapidity range |?|<0.8 as a function of event centrality in Pb-Pb collisions at vsNN=2.76TeV with ALICE at the LHC. The data are presented in the pTrange 0.1530GeV/c. In peripheral collisions (70-80%), only moderate suppression (RAA=0.6-0.7) and a weak pTdependence is observed. The measured nuclear modification factors are compared to other measurements and model calculations. © 2013 CERN.File in questo prodotto:
