Abstract
By making use of a non-perturbative definition of a momentum diffusioncoefficient as well as Heavy Meson Chiral Perturbation Theory, we investigatethe Brownian motion and kinetic equilibration of heavy quark flavours deep inthe confined phase. It appears that the momentum diffusion coefficient can beexpressed in terms of known low-energy constants; it increases rapidly attemperatures above 50 MeV, behaving as ~ T^7/F_pi^4 for m_pi / pi << T << F_pi,where m_pi and F_pi are the pion mass and decay constant, respectively. Theearly increase may suggest a broad peak in kappa/T^3 around the QCD crossover.For a more detailed understanding the computation could be generalized in anumber of ways.
