Abstract
We study nuclear modification of the photon-tagged jets in AA collisions within the jet quenching scheme based on the light-cone path integral approach to the induced gluon emission. The calculations are performed for running coupling. Collisional energy loss is treated as a perturbation to the radiative mechanism. We obtain a reasonable agreement with the recent data from the STAR Collaboration on the mid-rapidity nuclear modification factor IAA for Au+Au collisions at \(\sqrt s \)= 200 GeV for parametrization of running αs consistent with that necessary for description of the data on suppression of the high-pT spectra.
