Gauged supersymmetries in Yang-Mills theory

Understand

In this paper we show that Yang-Mills theory in the Curci-Ferrari-Delbourgo-Jarvis gauge admits some up to now unknown local linear Ward identities.

• These identities imply some non-renormalization theorems with practical simplifications for perturbation theory.
• We show in particular that all renormalization factors can be extracted from two-point functions.
• The Ward identities are shown to be related to supergauge transformations in the superfield formalism for Yang-Mills theory.
