Description
The ALICE experiment at the LHC has measured the transverse momentum spectra of neutral mesons via the two photon decay in pp and Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV over a wide transverse momentum range with different subsystems: with the electromagnetic calorimeters PHOS and EMCAL and via conversions of the photons in the inner material of the experiment to e+e--pairs reconstructed with the Central Tracking System.
In this talk, the production of neutral pions in pp and Pb-Pb collisions is compared in terms of the so called nuclear modification factor, $R_{AA}$, for different centrality selections of the Pb-Pb data sample.
