Abstract: Abstract Employing the QCD factorization formalism we compute $$ {B}_u^{-}\to {\gamma}^{\ast}\mathrm{\ell}{\overline{v}}_{\mathrm{\ell}} $$ B u − → γ ∗ ℓ v ¯ ℓ form factors with an off-shell photon state possessing the virtuality of order mb… read more here.

Abstract: We calculate the differential branching fraction, lepton forward-backward asymmetry and direct CP asymmetry for Bd,s → $$ \gamma \mathrm{\ell}\overline{\mathrm{\ell}} $$ decays with an energetic photon. We employ factorization methods, which result in rigorous next-to-leading order… read more here.
