Reexamining charmless B → PV decays in QCD factorization approach
Using the QCD factorization approach, we reexamine the two-body hadronic charmless B-meson decays to final states involving a pseudoscalar (P ) and a vector (V ) meson, with inclusion of the important penguin contractions of the spectator-scattering amplitudes induced by the b → Dg∗g∗ (with D = d or s, and g∗ denoting an off-shell gluon) transition, which are of order αs. Their impacts on the C...
متن کاملB?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 ...

متن کاملPhenomenological Analysis of Charmless Decays B→PV with QCD Factorization
We study hadronic charmless two-body B decays to final states involving pseudoscalar and vector mesons with the QCD factorization approach, including the contributions from the chirally enhanced power corrections and weak annihilations. The CP-averaged branching ratios and CP-violating asymmetries are given. Most of our results are in agreement with the present measurements, but the branching r...
متن کاملdecays within the factorization approach in QCD
Using the factorization approach and considering the contributions of the currentcurrent, QCD penguin and electroweak penguin operators at the leading approximation, the decay amplitudes and decay widths of Bq → Dq(D q)P and Bq → Dq(D q )V transitions, where q = u, d, s and P and V are pseudoscalar and vector mesons, are calculated in terms of the transition form factors of the Bq → Dq and Bq →...
