Description
We derive the leading modifications to transverse momentum broadening and medium-induced gluon spectrum in flowing matter for the case of a heavy flavor quark. We show that the broadening and radiation patterns acquire a new directional dependence arising from the interplay between the quark mass and the medium flow — an effect absent in the massless case. Consequently, the dead-cone effect is modified by the medium evolution, influencing the filling of the vacuum-vetoed region by medium-induced radiation. These results advance our understanding of how to construct heavy-flavor observables sensitive to the medium’s evolution, representing a key step towards imaging studies of the quark–gluon plasma in heavy-ion collisions using hard probes.
