摘要
We discuss infrared (IR) divergences in lepton mass renormalization in light-front quantum electrodynamics in Feynman gauge. We consider light-front quantum electrodynamics with Pauli-Villars fields and using old-fashioned time-ordered perturbation theory, we show that our earlier result regarding cancellation of true IR divergences up to O(e(4)) in coherent state basis holds in Feynman gauge also.
