Suppression of Particle Production at High pT in ALICE

The ALICE experiment has measured particle production in Pb-Pb collisions at √sNN =2.76 TeV during the first heavy-ion beam time at the CERNLHC in fall 2010. One of the most interesting observations in central collisions is a low nuclear modification factor RAA for unidentified charged particles with a strong pT dependence. Details of the analysis strategy as well as the construction of a pp reference at √s = 2.76 TeV are discussed. RAA is compared to results from the STAR and PHENIX experiments.
