Abstract

Invariant yields of neutral pions at midrapidity in the transverse momentum range 0.6 < pT < 12 GeV/c measured in Pb-Pb collisions at √sNN = 2.76 TeV are presented for six centrality classes. The pp reference spectrum was measured in the range 0.4 < pT < 10 GeV/c at the same center-of- mass energy. The nuclear modification factor, RAA, shows a suppression of neutral pions in central Pb-Pb collisions by a factor of up to about 8−10 for 5 . pT . 7 GeV/c. The presented measurements are compared with results at lower center-of-mass energies and with theoretical calculations.
