Heavy quark colorimetry of QCD matter
read the original abstract
We consider propagation of heavy quarks in QCD matter. Because of large quark mass, the radiative quark energy loss appears to be qualitatively different from that of light quarks at all energies of practical importance. Finite quark mass effects lead to an in-medium enhancement of the heavy-to-light D/\pi ratio at moderately large (5--10 GeV) transverse momenta. For hot QCD matter a large enhancement is expected, whose magnitude and shape are exponentially sensitive to the density of colour charges in the medium.

Energy Loss of a Heavy Quark in a Collisional Quark-Gluon Plasma
Including thermal parton collisions via the BGK kernel increases the collisional energy loss of a heavy quark in QGP by ~8% at large velocities for α_s=0.3 compared to the collisionless limit.
