New ways to explore factorization in b decays ∗
نویسنده
چکیده
We propose to study factorization breaking effects in exclusive b decays where they are strongly enhanced over the factorizing contributions. This can be done by selecting final-state mesons with a small decay constant or with spin greater than one. We find a variety of decay modes which could help understand the dynamical origin of factorization and the mechanisms responsible for its breaking. ∗Work supported by Department of Energy contract DE–AC03–76SF00515.

B?J/?(?,K) Decays within QCD Factorization Approach
We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
متن کاملCP Violation in B Decays within QCD Factorization
We analyze the extraction of weak phases from CP violation in B → π+π− decays. By combining the information on mixing induced CP violation in B → π+π−, namely Sππ, with the precision observable sin 2β obtained from the “gold-plated”mode B → ψKS, we propose the determination of the unitarity triangle. We also discuss alternative ways to analyze Sππ which can be useful if new physics affects Bd–B̄...
متن کاملProblems of QCD factorization in exclusive decays of B meson to charmonium
We study the exclusive decays of B meson into P-wave charmonium states χcJ(J = 0, 1) within QCD factorization approach and find that for B → χc1K decay, the factorization breaks down due to logarithmic divergences arising from nonfactorizable spectator interactions even at twist-2 order, and the decay rate is too small to accommodate the data, and that for B → χc0K decay, there are infrared div...
متن کاملHadronic B Decays to Charmless V T Final States
Charmless hadronic decays of B mesons to a vector meson (V ) and a tensor meson (T ) are analyzed in the frameworks of both flavor SU(3) symmetry and generalized factorization. We also make comments on B decays to two tensor mesons in the final states. Certain ways to test validity of the generalized factorization are proposed, using B → V T decays. We calculate the branching ratios and CP asym...
