Subtractive Renormalization of Strong-Coupling Quenched QED in Four Dimensions
Frederick T. Hawes, Tom Sizer, Anthony G. Williams
We study renormalized quenched strong-coupling QED in four dimensions in arbitrary covariant gauge, in the Dyson-Schwinger equation formalism. Above the chiral critical coupling, w…

Dyson-Schwinger equations and their application to nonperturbative field theory
F. T. Hawes, K. Kusaka, A. G. Williams
Two examples of recent progress in applications of the Dyson-Schwinger equation (DSE) formalism are presented: (1) Strong coupling quantum electrodynamics in 4 dimensions (QED)…
