Suppression of neutral pion production at large transverse momentum measured with the ALICE experiment in Pb-Pb collisions at TeV
The ALICE collaboration at the LHC has measured the transverse momentum
spectra of neutral pions via their two photon decay in pp and PbPb
collisions at TeV over a broad transverse momentum range
with different subsystems: with the electromagnetic calorimeters PHOS and EMCAL
and with photon conversions in the inner material of the detectors using
pairs reconstructed with the Central Tracking System. In this
report, neutral pions production is compared between pp and PbPb collisions
measured with conversion photons in terms of the nuclear modification factor,
, for different centrality selections of the PbPb data sample.Comment: 4 pages, 4 figures, proceedings of QM 201
