摘要：
In the framework of the electroweak theory, we discuss a class of gauge-fixing choices suitable for calculating electromagnetic processes. In particular, we show that with our choices, in addition to the basic Slavnov-Taylor identities guaranteeing that physical results are independent of the choice of the gauge fixing, we also have the standard Ward identities in quantum electrodynamics, which play a well-known crucial role in calculating electromagnetic processes and, specifically, in analyzing the electromagnetic radiative corrections.
