| Inclusive production of neutral pion in pp collisions at 0.9 and 7 TeV and perspectives for heavy-ion measurements with the ALICE calorimeters |

| Content: |
The ALICE experiment is equipped by two electromagnetic calorimeters. The Photon Spectrometer (PHOS) is a high-granularity electromagnetic calorimeter with a high energy resolution, designed for precise measurements of neutral mesons and direct photons in a wide kinematic range. The sampling lead-scintillator calorimeter (EMCAL) is a wide-aperture detector dedicated for jet measurements. During the 2010 pp run, the ALICE has recorded data with the integrated luminosity 10 ub^-1 at the collision energy 900 GeV and 20 nb^-1 at 7 TeV. Analysis of the calorimeters data allowed to measure inclusive pi0 spectrum at mid-rapidity in the transverse momentum range pT<8 GeV/c at sqrt(s)=900 GeV and pT<30 GeV/c at sqrt(s)=7 TeV. Preliminary results of the analysis and cross checks with other measurements performed at lower energies are presented. Reference data for the nuclear modification effects of pi0 production in Pb-Pb collisions at sqrt(s)=2.76 A*TeV are derived from the the pp measurements. The first analysis results of the ALICE heavy-ion run are presented. Perspectives for pi0 measurements with heavy ions are discussed. |
