How gauge covariance of the fermion and boson propagators in QED constrain the effective fermion-boson vertex
Shaoyang Jia, M. R. Pennington
We derive the gauge covariance requirement imposed on the QED fermion-photon three-point function within the framework of a spectral representation for fermion propagators. When sa…

Landau-Khalatnikov-Fradkin transformation for the fermion propagator in QED in arbitrary dimensions
Shaoyang Jia, M. R. Pennington
We explore the dependence of fermion propagators on the covariant gauge fixing parameter in quantum electrodynamics (QED) with the number of spacetime dimensions kept explicit. Gau…

Gauge covariance of the fermion Schwinger-Dyson equation in QED
Shaoyang Jia, M. R. Pennington
Any practical application of the Schwinger-Dyson equations to the study of -point Green's functions of a field theory requires truncations, the best known being finite order per…
