CP Violation and Flavour Mixing in the Standard Model -- 1996 Update

Abstract

We review and update the constraints on the parameters of the quark flavour mixing matrix $V_{CKM}$ in the standard model and estimate the resulting CP asymmetries in $B$ decays, taking into account recent experimental and theoretical developments. With the updated CKM matrix we present the currently-allowed range of the ratios $|V_{td}/V_{ts}|$ and $|V_{td}/V_{ub}|$, as well as the standard model predictions for the \bsbsbar\ mixing parameter $\text{xs}$ (or, equivalently, $\text{delms}$) and the quantities $\sin 2\alpha$, $\sin 2\beta$ and ${\sin }^2\gamma$, which characterize the CP-asymmetries in $B$-decays.
