Abstract:
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.
