Phenomenological Applications of Qcd Factorization to Semi-inclusive B Decays
We have systematically investigated the semi-inclusive B decays B → MX, which are manifestations of the quark decay b → Mq, within a framework inspired by QCD-improved factorization. These decays are theoretically clean and have distinctive experimental signatures. We focus on a class of these that do not require any form factor information and therefore may be especially suitable for extractin...
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 کاملExclusive and Semi-inclusive B Decays in QCD Factorization
Applications of QCD factorization to B → φK, charmless B → V V , B → J/ψK(K∗) and semi-inclusive decays B →MX are discussed.
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 کاملOn semi weak factorization structures
In this article the notions of semi weak orthogonality and semi weak factorization structure in a category $mathcal X$ are introduced. Then the relationship between semi weak factorization structures and quasi right (left) and weak factorization structures is given. The main result is a characterization of semi weak orthogonality, factorization of morphisms, and semi weak factorization structur...
