Description

We present a lattice dtermination of the heavy quark diffusion coefficient in 2+1 flavor QCD with almst physical quark masses in a wide temperature range. The momentum and spatial diffusion coefficients are extracted for a wide temperature range from $T=153$ MeV to $10$ GeV. The results are in agreement with previous work from the HotQCD collaboration and show fast thermalization of the heavy quark inside the QGP. Close to the chiral crossover temperature $T_c\simeq150$ MeV our results are close to the AdS/CFT bound calculated at strong coupling.
