摘要：
We compute the one-loop evolution of Weinberg's three-gluon CP violating vertex in a general 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 independent. The result is a suppression factor for the neutron electric dipole moment rather than enhancement. © 1990 The American Physical Society.
