“…Within this approach one can obtain a good description of 𝑅 𝐴𝐴 and 𝑣 2 of heavy mesons at the RHIC and the LHC energies [26]. Moreover, it is possible to compute the thermalization time of HQs in the QGP, or equivalently, the spatial diffusion coefficient, which turns out to be in fairly good agreement with the latest Lattice-QCD data, see [27] and references therein.…”

In ultrarelativistic nuclear collisions heavy quarks, charm and beauty, are produced almost immediately after the collision between the two colliding objects takes place. In fact, their production (proper) time can be estimated as 𝜏 form ≈ 1/2𝑚 where 𝑚 is the mass of the heavy quarks: this gives 𝜏 form ≈ 0.06 fm/c for charm and 𝜏 form ≈ 0.02 fm/c for beauty. Consequently, charm and beauty can probe the entire evolution of the system produced by the collision, including the very early stage in which the strong, coherent gluon fields, called the Glasma, dominate the dynamics. The early stage is then followed by the quark-gluon plasma stage, and finally by hadronization. We briefly review the recent developments on the diffusion and the energy loss of charm and beauty in ultrarelativistic heavy ion collisions, with particular emphasis on those in the early stage and on the estimate of the spatial diffusion coefficient of heavy quarks in the quark-gluon plasma.

Quasi-Particle Model (QPM) has been developed to study charm quark dynamics in ultra-relativistic heavy-ion collisions with good description of D mesons RAA(pT) and v2,3(pT) and leading to the evaluation of the spatial diffusion coefficient Ds(T). With an event-by-event full Boltzmann transport approach followed by a hybrid hadronization via coalescence plus fragmentation, we show RAA(pT), v2(pT) down to pT → 0 for D and B mesons. We find that QPM approach is able to correctly predict first available data on RAA(pT) and v2(pT) of single-electron from B mesons decays measured by ALICE. A significant breaking of the expected scaling of the thermalization time τth with MQ/T is found. Charm quark Ds(T) is about 50% larger than the asymptotic value for MQ → ∞, while the bottom Ds(T) is only 20% higher. In the infinite mass limit the Ds(T) is consistent with recent lQCD calculations with dynamical quarks.
