A new look at hadronic B decays
We present a detailed study of non-leptonic two-body decays of B mesons based on a generalized factorization hypothesis. We discuss the structure of non-factorizable corrections and present arguments in favour of a simple phenomenological description of their effects. We discuss tests of the factori...

| description | We present a detailed study of non-leptonic two-body decays of B mesons based on a generalized factorization hypothesis. We discuss the structure of non-factorizable corrections and present arguments in favour of a simple phenomenological description of their effects. We discuss tests of the factorization hypothesis and show how it may be used to determine unknown decay constants. In particular, we obtain f_{D_s}=(234\pm 25) MeV and f_{D_s^*}=(271\pm 33) MeV. |
