Abstract
We describe the propagation of heavy quarks (HQs), namely charm and bottom, in the quark-gluon plasma within an event-by-event full Boltzmann transport approach followed by a coalescence plus fragmentation hadronization. We discuss the extension to high-order anisotropic flows (vn(pT)) also evaluated within the Event-Shape Engineering technique which consists in selecting events in the same centrality class but characterized by different geometry in the initial state. In this context, we show prediction of correlations between different D-meson flow harmonics at LHC energies. In the same scheme, we extend our approach to study bottom quark dynamics: we find that QPM approach is able to correctly predict the first available data on RAA and v2 of single-electron from B decays. Within this approach we extract the space-diffusion coefficient Ds of heavy quarks, in particular discussing the comparison of our results with the lQCD calculation evaluated in the infinite mass limit. We find that our results in this limit are in good agreement with the recent lQCD data.
