Renormalization of the Cabibbo–Kobayashi–Maskawa matrix at one-loop level
Renormalization of the Cabibbo–Kobayashi–Maskawa matrix at one-loop level
We have investigated the present renormalization prescriptions of the Cabibbo–Kobayashi–Maskawa (CKM) quark-mixing matrix. Based on one prescription which is formulated by comparing with the fictitious case of no mixing of quark generations, we propose a new prescription which can make the physical amplitude involving quark mixing gauge independent and ultraviolet …
