Query: Self Energy Correction in Light Front QED And Coherent State Basis   We discuss the calculation of 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 electron mass renormalization $\delta m^2$ get canceled
up to $O(e^4)$ in Light Front gauge. We have also verified this cancellation in
Feynman gauge up to $O(e^2)$.
