Nuclear modification factor for light and heavy flavors within pQCD and recent data from the LHC
Abstract
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.
