Test of Factorization Hypothesis from Exclusive Non-leptonic B-Decays
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 th...
متن کاملNon leptonic B decays to axial - vector mesons and factorization
We present an analysis of two-body B decays with a pseudoscalar (P ) and an axial-vector meson (A) in the final state using factorization. We employ as inputs a limited number of experimental data, i.e. results for the B → K1γ , and B → K ∗γ radiative decays and the branching ratios for B → πρ, πK∗, Kρ, Kπ non leptonic decays. In this way we are able to compare our predictions with recent data ...
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 کاملFactorization in Non-leptonic Decays of Heavy Mesons
We propose a QCD-based model for calculation of the non-perturbative corrections to the factorization approximation in the decays of heavy mesons. In the framework of the model, factorization in pseudoscalar transitions holds exactly at the leading order leaving the opportunity to calculate non-leading corrections consistently.
متن کاملSemileptonic and non - leptonic B c decays
We make predictions for the exclusive semileptonic and the non-leptonic decay widths of the Bc meson. We evaluate the Bc semileptonic form factors for different decay channels in a relativistic model, and use factorization to obtain the non-leptonic decay widths. The recent discovery of the Bc meson by the CDF Collaboration [1] attracted a great deal of attention. The Bc meson is very interesti...
