Abstract
I present an update on the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements taking into account the current experimental and theoretical information on weak decays. The resulting fit is combined with the measured value of the B{sup 0}{sub d}-anti B{sup 0}{sub d} mixing ratio x{sub d} and estimates of the pseudoscalar coupling constants to determine the allowed range of the B{sup 0}{sub s}-anti B{sup 0}{sub s} mixing ration x{sub s} in the Standard Model (SM). For the central values of the parameters used we find 8 {<=} x{sub s} {<=} 24. Flavour changing neutral current (FCNC) B-decays are briefly reviewed; in particular the role of such decays in determining the CKM matrix elements V{sub td} and V{sub ts} is emphasized on the example of radiative B-decays, B {yields} (X{sub d} + {gamma}) and B {yields} (X{sub s} + {gamma}). (orig.).
