The Rare Radiative Annihilation Decays B̄ 0 s , d → J / ψγ

Abstract

We investigate the physics potential of the annihilation decays B̄0 s,d → J/ψ γ in the Standard Model and beyond. In naive factorization approach, the branching ratios are estimated to be B(B̄0 s → J/ψγ) = 1.40 × 10−6 and B(B̄0 d → J/ψγ) = 5.29 × 10−8. In the framework of QCD factorization, we compute the non-factorizable corrections and get B(B̄0 s → J… (More)
