  Heavy-flavor hadrons produced in ultra-relativistic heavy-ion collisions are
a sensitive probe for studying hadronization mechanisms of the
quark-gluon-plasma. In this work, we survey how different transport models for
the simulation of heavy-quark diffusion through a quark-gluon plasma in
heavy-ion collisions implement hadronization and how this affects final-state
observables. Utilizing the same input charm-quark distribution in all models at
the hadronization transition, we find that the transverse-momentum dependence
of the nuclear modification factor of various charm hadron species has
significant sensitivity to the hadronization scheme. In addition, the
charm-hadron elliptic flow exhibits a nontrivial dependence on the elliptic
flow of the hadronizing partonic medium.
