Infra-red divergences in Light Front Field Theory and Coherent State Formalism

High Energy Physics - Theory 2015-06-18 v1

Abstract

We discuss fermion self energy correction in light front QED using a coherent state basis. We show that if one uses coherent state basis instead of fock basis to calculate the transition matrix elements the true infrared divergences in δm2\delta m^2 get canceled up to O(e4)O(e^4) . We show this in Light-front as well as in Feynman gauge.
