Shadow fields and local supersymmetric gauges Original Research Article

To control supersymmetry and gauge invariance in super-Yang–Mills theories we introduce new fields, called shadow fields, which enable us to enlarge the conventional Faddeev–Popov framework and write down a set of useful Slavnov–Taylor identities. These identities allow us to address and answer the issue of the supersymmetric Yang–Mills anomalies, and to perform the conventional renormalization programme in a fully regularization-independent way.
