Abstract:
We point out that the measurements of the CP asymmetries in neutral B-decays together with a measurement of and the known value of can determine {\it all} elements of the Cabibbo-Kobayashi-Maskawa matrix without essentially any hadronic uncertainties. In particular the strong dependence of on () can be used to determine this element precisely. Consequently , and can also be determined. We derive a set of formulae which facilitate this study and we present a numerical analysis of several future scenarios. Accurate determinations of all parameters are expected from the B-factories and the Main Injector era at Fermilab including KAMI. An impressive accuracy should be reached in the LHC era. An analysis using Br(\kpnn) instead of Br(\klpnn) shows that although the determination of and this way is less accurate, still useful results for these elements can be obtained.- K0(L): semileptonic decay
