This chapter presents the extension of the gauge theory model of the weak interaction to describe the weak interaction decays of quarks. It introduces the Cabibbo angle and the more general scheme of CKM mixing. It describes the realization of parity, CP, and time reversal symmetries in a general theory of quark mixing. Finally, it pulls all of the strands of previous chapters together to write the full set of equations of the Standard Model of particle physics.

We study an ansatz for the quark mass matrix in which all of the nondiagonal entries are nonzero, but which still allows the quark mixing angles to be calculated in terms of ratios of quark masses and certain phases. Analytic calculations of the orthogonal rotation matrices in the up and down quark sectors and the resultant observed quark mixing matrix are presented. Comparison with experimental data is given.

Using the experimental value for the rate [Formula: see text], we derive constraints on the number of light neutrino species with the invisible width method in the framework of a left–right symmetric model (LRSM) and a E6 superstring model as a function of their respective mixing angles for the neutral vector gauge bosons. Using the above LEP result we get the constraints -1.6×10-3≤ ϕ ≤ 1.1 × 10-3 and -1.3 × 10-2 ≤ ϕE6 ≤ 0.4 × 10-2, which are stronger than those obtained in previous studies of these models.

We review the current status of the determination of the quark mixing angles |Vqq′|, where q=u, c; q′=d, s, b. We consider essentially exclusive decay processes, taking into account the main sources of uncertainties, the available calculations of flavor symmetry breaking for hadronic matrix elements and the possibilities of improvement offered by new experimental results. In some cases we provide full expressions for |Vqq′| in terms of measurable decay properties, which can be useful for new experimental data. Finally, we discuss briefly the effects on the unitarity tests of the Cabibbo-Kobayashi-Maskawa matrix when we consider recent corrections to the determination of |Vud|.
