    Submitted for publication in NIMThe ALICE experiment at LHC will detect and identify prompt photons and light neutral mesons with the PHOS and EMCal detectors. Charged particles will be detected and identified by the central tracking system. In this paper, a method to identify prompt photons and to separate them from the background of hadrons and decay photons in PHOS with the help of isolation cuts is presented

    Identification of photon-tagged jets in the ALICE experiment

    The ALICE experiment at LHC will detect and identify prompt photons and light neutral-mesons with the PHOS detector and the additional EMCal electromagnetic calorimeter. Charged particles will be detected and identified by the central tracking system. In this article, the possibility of studying the interaction of jets with the nuclear medium, using prompt photons as a tool to tag jets, is investigated by simulations. New methods to identify prompt photon-jet events and to distinguish them from the jet-jet background are presented.Comment: NIM A: accepted manuscrip

    We present in this paper the measured characteristics of a 64 lead–tungstate crystal array designed to detect high-energy photons and neutral mesons with the ALICE photon spectrometer PHOS. The array has been tested with electron and charged pion secondary beams delivered by the CERN PS and SPS synchrotrons. Photon energy and π0 invariant mass resolutions are presented. The PHOS particle identification performance for data simulated with the AliRoot package is studied
