We examine the relation between the damping rate of a chiral fermion mode propagating in a hot plasma and the rate at which the mode approaches equilibrium. We show that these two quantities, obtained from the imaginary part of the fermion self-energy, are equal provided the reaction rate is defined

Calculated in quantum electrodynamics (QED) and quantum chromodynamics (QCD) at high temperature, the damping rate of a mass shell moving fermion is known to present an infrared divergence due to unscreened magnetostatic modes. In this article, introducing a hard thermal loops (HTL) perturbative res
