Description
We compute the one-loop evolution of Weinberg's three-gluon CP-violating vertex in a general α≠0 gauge. We find that Weinberg's dimension-6 operator mixes with the Faddeev-Popov ghosts as well as with the quarks. Nevertheless the anomalous dimension of the three-gluon vertex is explicitly α independent. The result is a suppression factor for the neutron electric dipole moment rather than enhancement
