  Shower development dynamics for a jet traveling through the quark-gluon
plasma (QGP) is a multiscale process, where the heavy flavor mass is an
important scale. During the high virtuality portion of the jet evolution in the
QGP, emission of gluons from a heavy flavor is modified owing to heavy quark
mass. Medium-induced radiation of heavy flavor is sensitive to microscopic
processes (e.g. diffusion), whose virtuality dependence is phenomenologically
explored in this study. In the lower virtuality part of shower evolution, i.e.
when the mass is comparable to the virtuality of the parton, scattering and
radiation processes of heavy quarks differ from light quarks. The effects of
these mechanisms on shower development in heavy flavor tagged showers in the
QGP is explored here. Furthermore, this multiscale study examines dynamical
pair production of heavy flavor (via virtual gluon splittings) and their
subsequent evolution in the QGP, which is not possible otherwise. A realistic
event-by-event simulation is performed using the JETSCAPE framework.
Energy-momentum exchange with the medium proceeds using a weak coupling recoil
approach. Using leading hadron and open heavy flavor observables, differences
in heavy versus light quark energy-loss mechanisms are explored, while the
importance of heavy flavor pair production is highlighted along with future
directions to study.
