Ward identities in the light-cone gauge

Abstract

We check Ward identities in a special non covariant gauge, defined by nμ Aμ = 0, where n is a fixed vector subject to the condition nμ nμ = 0. Although this gauge would appear to be a special case of the planar gauge, one cannot pass continuously in the limit n2 → 0, from the latter to the light-cone gauge. The renormalization constants differ from the planar gauge; however, they give the same ratios, i. e. Ward identities identical to the ones in the axial gauge. The β-function is gauge invariant.
