Description
Using an event-by-event Boltzmann transport approach with an hadronization via coalescence plus fragmentation, we investigate charm dynamics and the extension to bottom (b) quark dynamics providing predictions for RAA and v2,3 of B mesons comparing to the data by ALICE collaboration. A sizeable v2,3 is found with important implications on bottomonium Υ production. The extension to b quark allows to investigate the mass dependence of Ds(T) towards the infinite mass limit assumed in lQCD. We find a significant breaking of the scaling of thermalization time τth with MQ/T, entailing a Ds for M → ∞ in agreement with the recent lQCD data with dynamical quarks. Furthermore, we extend our QPM approach to a more realistic model in which partonic propagators explicitly depend on quark momentum (QPMp). The QPMp improves the description of lQCD quark susceptibilities and entails a Ds with a stronger non-perturbative behaviour near to Tc which leads to a better agreement with the recent lQCD data.
