Description

We have investigated the many-body equations of $D$ and $\overline{B}$ mesons in a thermal medium by applying an effective field theory based on chiral and heavy-quark spin symmetries. Exploiting the same symmetries for the construction of the kinetic theory, we have derived an off-shell Fokker-Planck equation which incorporates information of the full spectral function of these states.

I will present the latest results on heavy-flavor transport coefficients below the chiral restoration temperature. I will also detail the origin of the in-medium reactions which contribute to the heavy-meson thermal width and energy loss, including the soft-pion emission (Bremsstrahlung) process.
