Abstract
We study the thermalization process of charm quarks in hot and dense matter. The diffusion of heavy quarks is calculated via a Langevin equation, both for a static medium as well as for a quark-gluon plasma (QGP) medium generated by a (3 1)-dimensional hydrodynamic model. We define two criteria for the thermalization of the heavy quarks and observe thermalization times that are longer than the lifetime of the QGP phase for reasonable values of the diffusion constant.
