Comment on "Dynamical mass generation in strongly coupled quantum electrodynamics with weak magnetic fields"

Abstract

In a recent article, Ayala et al. [Phys. Rev. D 73, 105009 (2006)] have studied the dynamical generation of masses for fundamental fermions in strongly coupled QED in the presence of weak magnetic fields. We argue that the results and conclusions of the article are not reliable as they are subject to gauge dependent artifacts resulting from an inconsistent truncation of the Schwinger-Dyson equations.
