Abstract
An attempt to define precisely the Feynman rules for Yang–Mills theories in the axial gauge is made by requiring consistency with the theories in covariant gauges. Line integrals of gauge potential are used to construct a fermion correlation function which is invariant under a restricted class of gauge transformations comprising the ones that relate axial to covariant gauges. It is found that the Cauchy principal value prescription for spurious singularities of the gauge field propagator violates the compatibility condition in the one-loop order of perturbation theory.
