Test of Factorization Hypothesis from Exclusive Non-leptonic B-Decays
نویسندگان
چکیده
We investigated the possibility of testing factorization hypothesis in nonleptonic exclusive decays of B-meson. In particular, we considered the nonfactorizable B 0 → D(∗)+D s modes and B → D(∗)+(π−, ρ) known as well-factorizable modes. By taking the ratios B(B → D(∗)+D s )/B(B → D(∗)+(π−, ρ)), we found that under the present theoretical and experimental uncertainties there’s no evidence for the breakdown of factorization description to heavy-heavy decays of the B meson.

QCD factorization for exclusive non - leptonic B - meson decays : General arguments and the case of heavy – light final states
QCD factorization for exclusive non-leptonic B-meson decays: General arguments and the case of heavy–light final states Abstract We provide a rigorous basis for factorization for a large class of non-leptonic two-body B-meson decays in the heavy-quark limit. The resulting factorization formula incorporates elements of the naive factorization approach and the hard-scattering approach , but allow...
متن کاملTowards a Theory of Charmless Non-leptonic Two-body B Decays
We address a number of theoretical and phenomenological issues in two-body charmless non-leptonic B decays in the context of a factorization model. A classification of the exclusive decays involving tree and penguin amplitudes is reviewed. The role of QCD anomaly in exclusive decays involving an η or η ′ is elucidated and comparison is made with the existing data. We argue that the factorizatio...
متن کاملIsospin Analysis of Two-body B Decays and Test of Factorization
It is shown that the existing data on two-body B decays, some of them only upper limits, are precise enough to perform an isospin analysis to extract the phase shifts due to final state interaction. Unlike charm decays, no significant final state interaction is observed in decays B → Dπ,Dρ, and Dπ supporting the factorization hypothesis in these decays. From the isospin amplitudes obtained, we ...
متن کاملNon-Leptonic Weak Decays of B Mesons
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. To evaluate the relevant transition form factors in the factorized decay amplitudes, we use information extracted from semilepto...
متن کاملNon - leptonic weak decays and final state interactions in lattice QCD ∗ †
Exclusive non-leptonic weak decays are a fundamental ingredient in the determination of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements and in the study of CP violation in the K-, Dand B-meson decays. However, the study of these non-leptonic decays involves nonperturbative aspects of the strong interactions, a challenging task for our still incomplete knowledge of non-perturbative dynamics....
