Abstract

International audience; Revisiting the fast fermion damping rate calculation in a thermalized QED and/or QCD plasma in thermal equilibrium at four-loop order, focus is put on a peculiar perturbative structure which has no equivalent at zero-temperature. Not surprisingly, and in agreement with previous C ⋆ -algebraic analyses, this structure renders the use of thermal perturbation theory more than questionable.
