    "abstract": "Charm- and bottom-quark rescattering in a Quark-Gluon Plasma (QGP) is\ninvestigated with the objective of assessing the approach towards\nthermalization. Employing a Fokker-Planck equation to approximate the collision\nintegral of the Boltzmann equation we augment earlier studies based on\nperturbative parton cross sections by introducing resonant heavy-light quark\ninteractions. The latter are motivated by recent QCD lattice calculations which\nindicate the presence of \"hadronic\" states in the QGP. We model these states by\ncolorless (pseudo-) scalar and (axial-) vector D- and B-mesons within a\nheavy-quark effective theory framework. We find that the presence of these\nstates at moderate QGP temperatures substantially accelerates the kinetic\nequilibration of c-quarks as compared to using perturbative interactions. We\nalso comment on consequences for $D$-meson observables in ultra-relativistic\nheavy-ion collisions.",
