Renormalization of the Cabibbo-Kobayashi-Maskawa Matrix
Using the on-shell scheme and the general linear Rξ gauge we have calculated the one-loop amplitude W + → uI d̄j . In agreement with previous work we have shown that the Cabibbo-Kobayashi-Maskawa (CKM) matrix ought to be renormalized. We show how to renormalize the CKM matrix and, at the same time, obtain a gauge independent W decay amplitude. PACS number(s): 11.10.Gh, 12.15.-y, 12.15.Ff, 12.15....
متن کاملA Novel Formulation of Cabibbo-Kobayashi-Maskawa Matrix Renormalization
We present a gauge-independent quark mass counterterm for the on-shell renormalization of the Cabibbo-Kobayashi-Maskawa (CKM) matrix in the Standard Model that is directly expressed in terms of the Lorentz-invariant self-energy functions, and automatically satisfies the hermiticity constraints of the mass matrix. It is very convenient for practical applications and leads to a gauge-independent ...
متن کاملSimple approach to renormalize the Cabibbo-Kobayashi-Maskawa matrix.
We present an on-shell scheme to renormalize the Cabibbo-Kobayashi-Maskawa (CKM) matrix. It is based on a novel procedure to separate the external-leg mixing corrections into gauge-independent self-mass and gauge-dependent wave function renormalization contributions, and to implement the on-shell renormalization of the former with nondiagonal mass counterterm matrices. Diagonalization of the co...
متن کاملNew standard parametrization of the Cabibbo-Kobayashi-Maskawa matrix.
We propose a new parametrisation of the Cabibbo-Kobayashi-Maskawa Matrix in which the approximations of the standard parametrisation, |Vcb| ≈ s23, |Vus| ≈ s12, are promoted to exact results. There are myriad possible parametrisations of the Cabibbo-Kobayashi-Maskawa (CKM) Matrix V [1]. One particular parametrisation [2] has recently been advocated by the Particle Data Group (PDG) [3] as a “stan...
متن کاملExploring inconsistencies with the Cabibbo-Kobayashi-Maskawa model
A small upper-bound is obtained for the CP phase δ in a CKM matrix, | sin δ| < 0.44 based on CP independent data on |Vub/Vcb| alone. Potential inconsistencies with the CKM model in existing data which need a theory beyond the standard model to overcome emerge in the analysis using this CKM matrix. In addition, all CP asymmetry measurables for the Bd− B̄d system are expressed solely by the CP pha...
