Jet Quenching for Heavy Flavors in AA and pp Collisions

We perform a global analysis of experimental data on jet quenching for heavy flavors for scenarios with and without quark-gluon plasma formation in pp collisions. We find that the theoretical predictions for the nuclear modification factor RAA for heavy flavors at the LHC energies are very similar for these scenarios, and the results for RAA and $${{{v}}_{2}}$$ agree reasonably with the LHC data. The agreement with data at the RHIC top energy becomes somewhat better for the intermediate scenario, in which the quark-gluon plasma formation in pp collisions occurs only at the LHC energies. Our fits to heavy flavor RAA show that description of jet quenching for heavy flavors requires somewhat bigger αs than data on jet quenching for light hadrons.
