Invariant yields of neutral pions at midrapidity in the transverse momentum range 0.6<pT<12 GeV/c measured in Pb–Pb collisions at root(s_NN)= 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, R_AA, 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.
