Abstract: (Springer)

Invariant yields of neutral pions at midrapidity in the transverse momentum range 0.6 < p_\mathrm{T}< 12\,{\mathrm \mathrm{GeV}}/ c measured in Pb–Pb collisions at

\sqrt{s_{\mathrm {NN}}}= 2.76\,{\mathrm {\,}}\mathrm{TeV}

are presented for six centrality classes. The pp reference spectrum was measured in the range

0.4 < p_\mathrm{T}< 10\,{\mathrm {\,}}\mathrm{GeV}/

c at the same center-of-mass energy. The nuclear modification factor,

R_\mathrm{{AA}}

, shows a suppression of neutral pions in central Pb–Pb collisions by a factor of up to about

8{-}10

for 5 \lesssim p_\mathrm{T}\lesssim 7\,{\mathrm \mathrm{GeV}}/ c. The presented measurements are compared with results at lower center-of-mass energies and with theoretical calculations.
