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 کاملThe Supersymmetric QCD Radiative Corrections to Top Quark Semileptonic Decays
The one-loop supersymmetric QCD corrections to the top quark semileptonic decays t → b l̄ νl are considered. The corrections are found to reduce the decay width. In the still acceptable parameter space the corrections to the percentage change in top quark semileptonic decay width can reach the level of -0.7%. PACS numbers: 11.30.Pb, 12.38.Bx, 14.65.Ha Keyword(s): SUSY QCD, RADIATIVE CORRECTIONS,...

using qcd factorization for the hadronic matrix elements, we show that existing data, inparticular the branching ratios br ( b →j/ψk) and br ( b →j/ψπ), can be accounted for in this approach.we analyze the decay b j /k( ) within the framework of qcd factorization. the calculation of therelevant hard-scattering kernels for twist-2 and twist-3 is completed. we calculate this decay in a special...
متن کاملDecays in QCD Factorization
The hadronic decay B → J/ψK∗ is analyzed within the framework of QCD factorization. The spin amplitudes A0, A‖ and A⊥ in the transversity basis and their relative phases are studied using various different form-factor models for B −K∗ transition. The effective parameters a2 for helicity h = 0,+,− states receive different nonfactorizable contributions and hence they are helicity dependent, contr...
متن کاملThe role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays
This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
