Studies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays
We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
متن کاملB 0 s → K + K − and B 0 s → K 0 K̄ 0 Decays within Supersymmetry
We compute the supersymmetric (SUSY) contributions to the observables in B s → KK and B s → KK̄ decays. The hadronic parameters in the standard-model (SM) amplitudes are obtained from the B d → KK̄ decay using a recent approach that combines flavor SU(3) symmetry and a controlled input from QCD factorization. The latest experimental data for BR(B s → KK) is in agreement with the SM prediction. We...
متن کاملObservation of the Decays B 0 → K + π − π 0 and B 0 → ρ − K + . Belle Collaboration
We report the observation of B0 decays to the K+π−π0 final state using a data sample of 78 fb−1 collected by the Belle detector at the KEKB e+e− collider. With no assumptions about intermediate states in the decay, the branching fraction is measured to be (36.6 −4.3 ± 3.0) × 10−6. We also search for B decays to intermediate two-body states with the same K+π−π0 final state. Significant B signals...
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 ...
