γ+Jet events provide a, tomographic measurement of the medium formed in heavy ion collisions at LHC energies. Tagging events with a well identified high PT direct photon and measuring the correlation distribution of hadrons emitted oppositely to the photon in ALICE, allows us to determine, with a good approximation, both the jet fragmentation function and the back-to-back azimuthal alignment of the direct photon and the jet. Comparing these two observables measured in pp collisions with the ones measured in AA collisions will reveal the modifi...
