We calculate the energy loss and angular radiation distribution for heavy quark propagating through the quark-gluon plasma at the LHC in the framework of the QCD extended Moller theory i.e. BDMPS formalism plus large Coulomb logarithms. We study the role of Coulomb Logarithms in heavy quark propagation. We calculate the energy loss and estimate the Quenching Weights both including the phase space constraints, and neglecting them.
In the limit of massless quarks, our results for energy loss coincide with the previously known ones. We show that for heavy quarks the Coulomb gluons feel the dead cone, and lead to significant improvement of the agreement between theoretical prediction and experimental data for heavy quark quenching weights.
