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...

B Decays to D

The e + e − annihilation data recorded with the BABAR detector has been used to study B 0 decays to D (*)+ s and D * − mesons. The production fraction of inclusive D (*)+ s and the corresponding momentum spectra have been determined. Exclusive decays B 0 → D * − D (*)+ s have been identified with a partial reconstruction technique and their branching ratios have been measured. Fully reconstruct...

Measurement of CP Violation in B^{0}→D^{+}D^{-} Decays.

The CP violation observables S and C in the decay channel B^{0}→D^{+}D^{-} are determined from a sample of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, collected by the LHCb experiment and corresponding to an integrated luminosity of 3  fb^{-1}. The observable S describes CP violation in the interference between mixing and the decay amplitude, and C parametrizes direct CP...

Theoretical Analysis of ¯B → D ∗ ∗ π Decays

The decays ¯ B → D * * π, where D * * is a narrow p-wave charm resonance, are investigated in the context of a generalized factorization hypothesis, including the leading nonfactorizable corrections. The decay rates for these processes are related to the corresponding semileptonic rates at maximum recoil. It is pointed out that the current data on the branching ratio for the decay B − → D * 0 2...
