| Abstract: | We analyze the impact of the forthcoming CP-violating observables in the Bs → K+K- system, combined with the precise measurement of sin 2β, in the extraction of the CKM matrix. Computing the penguin parameters (r, θ) within QCD factorization yields a precise determination of  , reflected by a weak dependence on θ, which is shown to be a second order effect. Using the SU(3)-flavour symmetry argument and the current B-factories data provided by the Bd → π+π- modes, we complement the Bs → K+K- CP-violating observables in a variety of ways, in particular we find that SKK > 0. Finally, we investigate systematically the SU(3)-symmetry breaking factor within QCD factorization. LMU 12/04 |
