n. The analytic expression generalizes the GLV opacity expansion for massless quanta to
heavy quarks with mass M in a QCD plasma with a gluon dispersion characterized by an
asymptotic plasmon mass, mg= gT/2. Remarkably, we find that the general result is obtained
by simply shifting all frequencies in the GLV series by (mg2+ x2M2)/(2xE). Numerical
evaluation of the first order in opacity energy loss shows that both charm and bottom energy …
