On Quantum Fields at High Temperature
arXiv:1901.06338 · doi:10.3390/universe5010026
Abstract
Revisiting the fast fermion damping rate calculation in a thermalized QED and/or QCD plasma at 4-loop order, focus is put on a peculiar perturbative structure which has no equivalent at zero-temperature. Not surprisingly and in agreement with previous -algebraic analyses, this structure renders the use of thermal perturbation theory quite questionable.
