By utilizing a soft-hard factorized model, which combines a thermal perturbative description of soft scatterings and a perturbative QCD-based calculation for hard collisions, we study the energy and temperature dependence of the heavy quark diffusion coefficients in Langevin dynamics. The adjustable parameters are fixed from the comprehensive model-data comparison. We find that a small value of the spatial diffusion coefficient at transition temperature is preferred by data. With the parameter-optimized model, we are able to describe simultaneously the promptanddata atGeV in Pb–Pb collisions atandTeV. We also make predictions for non-promptmeson for future experimental tests down to the low momentum region.
