Ward-Slavnov identities in the axial gauge

Abstract

A new derivation of the Ward-type identities for non-Abelian gauge theories in the axial gauge is given. The merit of this derivation is its extreme simplicity. It makes the basic feature of this gauge transparent and allows an extension, in a trivial manner, of the identities on the renormalization constants, written down by Kummer, to the case in which fermions are also included.
