Collisional vs. radiative energy loss of heavy quark in a hot and dense nuclear matter


Journal Article

We study the heavy quark evolution in a quark-gluon plasma medium within the framework of Langevin equation coupled to a (2 + 1)-dimensional viscous hydrodynamic model. We modify the current Langevin algorithm such that apart from quasi-elastic scattering, medium-induced radiative energy loss is incorporated as well by treating gluon radiation as an extra force term. We find a significant effect of gluon radiation on heavy quark energy loss at LHC energies. Our calculation provides a good description of the D meson suppression measured by ALICE experiment, and makes a prediction for B meson suppression and flow. © 2013 Elsevier B.V.
