Query: Langevin dynamics of heavy quarks in a soft-hard factorized approach   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 $2\pi TD_{s}(T_{c}) \simeq 6$. With the parameter-optimized
model, we are able to describe simultaneously the prompt $D^{0}$ $R_{\rm AA}$
and $v_{2}$ data at $p_{\rm T}\le8$ GeV in Pb--Pb collisions at $\sqrt{s_{\rm
NN}}=2.76$ and $\sqrt{s_{\rm NN}}=5.02$ TeV. We also make predictions for
non-prompt $D^{0}$ meson for future experimental tests down to the low momentum
region.
