Abstract
ALICE, A Large Ion Collider Experiment, is dedicated to study the QCD matter at extreme high temperature and density to understand the Quark Gluon Plasma (QGP) and phase transition. High-transverse-momentum photons and neutral mesons from the initial hard scattering of partons can be measured with ALICE calorimeters, PHOS (PHOton Spectrometer) and EMCAL (ElectroMagnetic CALorimeter). Combing the additional central tracking detectors, the γ-jet and π0-jet measurements thus can be accessed. These measurements offer us a sensitive tomography probe of the hot-dense medium generated in the heavy ion collisions. In this paper, high pT and photon physics is discussed and the ALICE calorimeters capabilities of high-transverse-momentum neutral mesons and γ-jet measurements are presented.
