报告摘要： Heavy quarks are produced in the early stages of the ultra-relativistic heavy-ion collisions and probe the produced hot medium created in these collisions through its entire evolution. The kinetic thermalization of heavy quarks can be characterized by the heavy quark diffusion coefficient. In this talk I will report the determinations of this coefficient from different measurements in both quenched lattice QCD and 2+1 flavor lattice QCD. The talk is based on [1,2,3].
