Transverse vertices in electrodynamics and the gauge technique
journal contribution
posted on 2023-05-18, 04:57 authored by Robert DelbourgoRobert Delbourgo, Zhang, RThe inclusion of transverse vertex corrections in the gauge technique, needed for the restoration of gauge covariance, results in a self-consistent equation for the source propagator spectral function which agrees with perturbation theory when expanded to order e4. The authors have managed to solve the equation in the infrared and ultraviolet limits, for scalar and spinor sources, in an arbitrary covariant gauge. The gauge covariance at asymptopia is thus established.
