Ward identities for rigid symmetries of higher order

Abstract

Higher order conservation laws, associated with conserved antisymmetric tensors $j^{{\mu }_1...{\mu }_k}$ fulfilling ${\partial }_{{\mu }_1}{j}^{{\mu }_1...{\mu }_k}\approx 0$, are shown to define rigid symmetries of the master equation. They thus lead to independent Ward identities which are explicitly derived.
