Abstract
In their recent letter, Heeck et al. [Phys. Rev. D 108, L031703] introduced a simple model of leptogenesis, in which the asymmetry originates from the scattering processes only. Here we argue that their calculation violates some of the basic principles of perturbative quantum field theory.PDF: Comment on "Dirac leptogenesis via scatterings".pdf
