摘要：

We derive the two-loop evolution equations for the Cabibbo-Kobayashi-Masakawa (CKM) matrix. We show that to leading order in the mass and CKM hierarchies the scaling of the mixings \V(ub\2, \V(cb)\2, \V(td)\2, \V(ts\2 and of the rephase-invariant CP-violating parameter J is universal to all orders in perturbation theory. In leading order the other CKM elements do not scale. Imposing the constraint lambda(b) = lambda(r), at the grand unified theory scale determines the CKM scaling factor to be congruent-to 0.58 in the minimal supersymmetric standard model.
