Abstract
Ward identities are derived in a general axial gauge by considering three distinct expressions for the gauge-breaking part of the Yang-Mills Lagrangian. The Ward identities are verified by calculating the one-loop self-energies in the appropriate axial gauge. It is shown, in particular, that one of the three gauge-breaking terms, namely (2..cap alpha..n/sup 2/)/sup -1/(nxA/sup a/)partial/sup 2/(nxA/sup a/), gives rise to a self-energy which is nontransverse. The latter gauge includes the planar gauge (..cap alpha.. = -1). The effect of the general axial gauge on the Yang-Mills counterterms is analyzed and the implications for quantum gravity are briefly discussed.
