摘要：

In this paper we give a convenient expression for the one-loop vertex correction in Yennie gauge QED. We use dimensional regularization to regulate ultraviolet and potential infrared divergences. We study the infrared behavior of the vertex correction in a class of simple covariant gauges, and verify that beta = 2/(1 - 2 epsilon) is the appropriate choice for the gauge parameter of the Yennie gauge (where n = 4 - 2 epsilon is the dimensionality of spacetime).
