چکیده
We study the rare decays of B + c → D (*)+ q l ¯ l (q = d, s and l = ν l , e, µ, τ) in the standard model. The form factors are evaluated in the light front and constituent quark models, respectively. We find that the decay branching ratios calculated in the two models for B + c → D + q l ¯ l agree well with each other, whereas those for B

Study of B s → ( η , η ′ , φ ) l l̄
We study the rare decays of B s → M s ℓ ¯ ℓ (M s = η, η ′ , φ and ℓ = ν, e, µ, τ) in the standard model. With the hadronic form factors evaluated in the light front and constituent quark models, we estimate the decay branching ratios, respectively. We also discuss the longitudinal lepton polarization and forward-backward asymmetries.
متن کامل|Vub| from exclusive B and D decays.
We propose a model-independent method to determine the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element |Vub| from exclusive B and D decays. Combining information obtainable from B → ρ l ν̄l, B → K∗ ν ν̄, D → ρ l̄ νl and D → K∗ l̄ νl, a determination of |Vub| is possible, with an uncertainty from theory of around 10%. Theoretical uncertainties in the B → K∗ l l̄ decay rate are discussed. ∗W...
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 ...

متن کاملComment on Vub from Exclusive Semileptonic B and D Decays
The prospects for determining |Vub| from exclusive B semileptonic decay are discussed. The double ratio of form factors (f (B→ρ)/f (B→K ∗))/ (f (D→ρ)/f (D→K ∗)) is calculated using chiral perturbation theory. Its deviation from unity due to contributions that are non-analytic in the symmetry breaking parameters is very small. Combining experimental data obtainable from B → ρ l ν̄l, B → Kl l̄ and ...
