One-Loop Electron Vertex in Yennie Gauge

High Energy Physics - Phenomenology 2009-01-07 v3

Abstract

We derive a compact Yennie gauge representation for the off-shell one-loop electron-photon vertex, and discuss it properties. This expression is explicitly infrared finite, and it has proved to be extremely useful in multiloop calculations in the QED bound state problem.
