In ultrarelativistic nuclear collisions heavy quarks are produced out of thermal equilibrium in the very early stage of the reaction and their thermalization time was expected to be considerably larger than that of light quarks. On the other hand, a strongly-interacting QGP can be envisaged in the heavy quark sector due to the presence of heavy-light hadron-like resonances in the QGP for temperatures up to ∼2 TC. We investigate the consequences of such states employing a relativistic Langevin simulation. Hadronization is modeled by a coalescence-fragmentation scheme. We present the predictions for the nuclear modification factor and elliptic flow of D and B mesons at LHC energies and compare the results with the successful predictions of this model for RHIC conditions. We find similar heavy-quark thermalization effects at LHC and RHIC.
