Comment on the paper: ``Feynman-Schwinger representation approach to nonperturbative physics'' by C. Savkli et al. [Phys. Rev. C 60, 055210 (1999), hep-ph/9906211]
R. Rosenfelder, A. W. Schreiber
We point out that the scalar Wick-Cutkosky model (with interaction) used in this study has been known for a long time to be unstable. However, the numerical results present…

Dimensionally Regularized Study of Nonperturbative Quenched QED
Andreas W. Schreiber, Tom Sizer, Anthony G. Williams
We study the dimensionally regularized fermion propagator Dyson-Schwinger equation in quenched nonperturbative QED in an arbitrary covariant gauge using the Curtis-Pennington verte…
