Abstract: (Elsevier)
We describe a non-perturbative study of the infrared behavior of the axial gauge gluon propagator based on the Dyson equation and Ward identities. We conclude that the propagator Δ μν ( q ) displays a q −4 singularity in the infrared limit, and that consequently the axial gauge running coupling constant g A 2 )( q ) displays a q −2 singularity in the same limit. The only assumption necessary to obtain this conclusion is that the transverse part of the triple-gluon vertex function does not dominate the longitudinal part in the infrared regime.- GAUGE FIELD THEORY: YANG-MILLS
