Aspects of QCD Factorization
نویسنده
چکیده
The QCD factorization approach provides the theoretical basis for a systematic analysis of nonleptonic decay amplitudes of B mesons in the heavy-quark limit. After recalling the basic ideas underlying this formalism, several tests of QCD factorization in the decays B → D(∗)L, B → K∗γ, and B → πK,ππ are discussed. It is then illustrated how factorization can be used to obtain new constraints on the parameters of the unitarity triangle.

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 ...
متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...

متن کاملConceptual aspects of QCD factorization in hadronic B decays ∗
I review the meaning of “QCD factorization” in hadronic two-body B decays and then discuss recent results of theoretical (rather than phenomenological) nature: the proof of factorization at two loops; the identification of “chirally enhanced” power corrections; and the role of annihilation contributions.

This paper studies improved factorization method, in the heavy quark limit, for B→Kπ decays. Paying attention to strong interaction scale AQCD, and calculating all parameters depending on that in the particular scale (the same as µ ) show that we can obtain better and comparable results for branching ratios such as BR(B0 → K0 π 0 )=8.5+0.7-0.5 × 10-6 and BR(B →π k0)=2.26+0.17-0.15 × 10-5, and...
