Factorization versus duality in nonleptonic decays: A quark model approach.
Abstract We study in a quark model the contradiction between factorization and duality found in nonleptonic decays at next to leading order in 1/Nc, concentrating on quark exchange mechanism. The contradiction originates in the fact that the standard factorization assumption approximates the asymptotic final states by a non-orthogonal set of states, thus leading to an overcounting of the decay ...
متن کاملNonleptonic Weak Decays of Bottom Baryons
Cabibbo-allowed two-body hadronic weak decays of bottom baryons are analyzed. Contrary to the charmed baryon sector, many channels of bottom baryon decays proceed only through the external or internal W -emission diagrams. Moreover, W -exchange is likely to be suppressed in the bottom baryon sector. Consequently, the factorization approach suffices to describe most of the Cabibbo-allowed bottom...
متن کاملQcd-improved Factorization in Nonleptonic B Decays
Nonleptonic decays ofB mesons have attracted a lot of attention recently since they were observed experimentally in CLEO, BaBar and BELLE. These decays are important in extracting the information on the Cabibbo-KobayashiMaskawa (CKM) matrix elements and CP violation. On the theoretical side, it is the least understood area. Since nonleptonic decays involve nonperturbative effects such as final-...
متن کاملNonleptonic weak decays of charmed mesons.
A previous analysis of two-body Cabibbo allowed nonleptonic decays of D mesons and of Cabibbo allowed and first-forbidden decays of D and D s has been adjourned using more recent experimental data and extended to the Cabibbo forbidden decays of D. Annihilation and W-exchange contributions as well as final state interaction effects (assumed to be dominated by nearby resonances) have been include...
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 ...
