Query: $D$-mesons propagation in hadronic matter and consequences on
  heavy-flavor observables in ultrarelativistic heavy-ion collisions   We employ recently published cross sections for $D$-mesons with hadrons and
calculate the drag and diffusion coefficients of $D$-mesons in hadronic matter
as a function of the momentum of $D$-mesons as well as of the temperature of
the medium. Calculating in our approach the spatial diffusion coefficient,
$D_x$, at zero chemical potential we see a very smooth transition between our
calculations for the hadron gas and the lattice QCD calculations. Applying the
results for the transport coefficients of $D$-mesons in a Fokker-Planck
equation, which describes the evolution of $D$-mesons during the expansion of a
hadron gas created in ultrarelativistic heavy-ion collisions, we find that the
value of $R_{AA}$ is little influenced by hadronic rescattering, whereas in the
elliptic flow the effects are stronger. We extend our calculations to the
finite chemical potentials and calculate the spatial diffusion coefficients of
$D$-mesons propagating through the hadronic medium following isentropic
trajectories, appropriate at future FAIR and NICA heavy-ion experiments. For
the isentropic trajectory with $s/\rho_B^{\rm net}=20$ we find a perfect
matching of results for $D$-mesons in hadronic matter and for charm quarks in
partonic matter treated within the DQPM approach.
