Description

We derive the two-loop evolution equations for the Cabibbo-Kobayashi-Maskawa (CKM) matrix. We show that to leading order in the mass and CKM hierarchies the scaling of the mixings |Vub|2,|Vcb|2,|Vtd|2, |Vts|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 λb=λτ at the grand unified theory scale determines the CKM scaling factor to be congruent 0.58 in the minimal supersymmetric standard model
