We review and update the constraints on the parameters of the quark fl
avour mixing matrix V-CKM in the standard model (SM) and estimate the
resulting CP asymmetries in B decays, taking into account recent exper
imental and theoretical developments. With the updated CKM matrix we p
resent the currently-allowed range of the ratios \V-td/V-ts\ and \V-td
/V-ub\, as well as the SM predictions for the B-s(0)-<(B-s(0))over bar
> mixing parameter x(s) (or, equivalently, Delta M(s)) and the quantit
ies sin 2 alpha, sin 2 beta and sin(2) gamma, which characterize CP as
ymmetries in B-decays.
