Suppression of neutral pion production at large transverse momentum measured with the ALICE experiment in Pb-Pb collisions at $sqrt{s_{NN}}=2.76$ TeV

The ALICE collaboration at the LHC has measured the transverse momentum spectra of neutral pions via their two photon decay in pp and Pb$-$Pb collisions at $sqrt{s_{NN}}=2.76$ TeV over a broad transverse momentum range with different subsystems: withthe electromagnetic calorimeters PHOS and EMCAL and with photon
