Mixing angles and CP violation in an SU(2)/sub L/ x U(1) gauge model

Journal Article · · Phys. Rev., D; (United States)
Expressions for the mixing parameters are obtained in terms of mass ratios in the standard Weinberg-Salam model with permutation symmetry S/sub 3/ for six quarks. The CP-violating phase delta is taken into account and there are no arbitrary parameters except for the quark masses. In the lowest order, the angles defined by Kobayashi and Maskawa are sintheta/sub 1/ approx. = (m/sub d//(m/sub d/+m/sub s/))/sup 1/2/, sintheta/sub 2/ approx. = -((m/sub s//m/sub b/)/sup 2/-(m/sub c//m/sub t/)/sup 2/)/sup 1/2/, and sintheta/sub 3/=(m-italic/sub s//m/sub b/)/sup 2//costheta/sub 1/. The model can be consistent with the observed magnitude of CP violation. The b quarks decay predominantly into c quarks with lifetime of tau/sub b/ approx. = 10/sup -11/ sec.
