dc.description.abstract | The procedure for the energy calibration of the high granularity electromagnetic calorimeter PHOS of the ALICE experiment is presented. The methods used to perform therelative gain calibration, to evaluate the geometrical alignment and the corresponding correction of the absolute energy scale, to obtain the nonlinearity correction coefficients and finally, tocalculate the time-dependent calibration corrections, are discussed and illustrated by the PHOS performance in proton-proton (pp) collisions at √s=13TeV. After applying all corrections, the achieved mass resolutions for π0 and η mesons for pT>1.7GeV/c are σπ0m=4.56±0.03MeV/c2 and σηm=15.3±1.0MeV/c2, respectively | en |
