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… 
Generic one-loop matching conditions for rare meson decays
Abstract Leptonic and semileptonic meson decays that proceed via flavour-changing neutral currents provide excellent probes of physics of the standard model and beyond. We present explicit results

The 1.5 Order Formalism does not Generate a Valid BRS Transformation for Supergravity
The 1.5 order formalism (sometimes called a ‘trick’) is the cornerstone of modern supergravity. In this paper, the free massive Wess Zumino theory is used as a simple toy model to look at the BRS
A Candidate for a Supergravity Anomaly
Using elementary BRS cohomology theory, this paper describes a supergravity anomaly analogous to, but very different from, the well known gauge and gravitational anomalies. The form of the anomaly is

Quantum Field Theory
Quantum field theory is the framework in which the regnant theories of the electroweak and strong interactions, which together form the standard model, are formulated. Quantum electrodynamics (QED),
