We examine the flavor dependence
of the nuclear modification factor RAA in the pQCD
calculations at LHC energies. The computations are performed accounting for
radiative and collisional
parton energy loss with running coupling constant.
Our results show that the recent LHC data on the RAA for
charged hadrons, D-mesons, and non-photonic
electrons agree reasonably with
the pQCD picture of the parton energy loss with
the dominating contribution from the radiative mechanism.
