Test of Gauge Covariance of Fermion-Photon Vertex in Quenched, Massless Three Dimensional Quantum Electrodynamics

arXiv:hep-th/9807036

Abstract

We study the gauge covariance of the fermion-photon vertex in quenched, massless 3-dimensional quantum electrodynamics. A class of vertex Ansätze obtained by generalizing that proposed by Dong et al. is tested using the invariance of the photon polarization scalar under the Landau-Khalatnikov transformation.
