Exclusive Hadronic B-Decays
Abstract
Exclusive non-leptonic two-body decays are discussed on the basis of a generalized factorization approach which also includes non-factorizeable contributions. Numerous decay processes can be described satisfactorily. The success of the method makes possible the determination of decay constants from non-leptonic decays. In particular, we obtain fDs=(234+-25) MeV and fD*s=(271+-33) MeV. The observed constructive and destructive interference pattern in charged B- and D-decays, respectively, can be understood in terms of the different alphas-values governing the interaction among the quarks. The running of alphas is also the cause of the observed strong increase of the amplitude of lowest isospin when going to low energy transitions.
