摘要

We consider the effect of the chromo-electromagnetic field fluctuations in addition to the collisional as well as the radiative energy losses suffered by heavy quarks while propagating through the hot and dense deconfined medium of quarks and gluons created in relativistic heavy ion collisions. The chromo-electromagnetic field fluctuations play an important role as they lead to an energy gain of heavy quarks of all momenta and are significant at low momentum. We include the effect of these fluctuations, for the first time, while computing the nuclear modification factor (R-AA) of heavy mesons, viz., D mesons and B mesons, and compare with the experimental measurements in Pb-Pb collisions at root s(NN) = 2.76 and 5.02 TeV by the CMS and ALICE experiments at the CERN Large Hadron Collider. Our results are found to be in very good agreement with the measurements.
