Semileptonic B(s)→α1(K1)ℓ+ℓ- decays via the light-cone sum rules with B-meson distribution amplitudes

Semileptonic B(s)→α1(K1)ℓ+ℓ- decays via the light-cone sum rules with B-meson distribution... The form factors of semileptonic B(s)→a1(K1)ℓ+ℓ-, ℓ=τ, μ, e transitions are investigated in the framework of the light-cone sum rules with B-meson distribution amplitudes, which play an important role in exclusive B decays. The B-meson distribution amplitudes, φ±(ω) are a model-dependent form, so we consider four different parametrizations which can provide a reasonable description of φ±(ω) from QCD corrections. The branching fractions of these transitions are calculated. For a better analysis, a comparison of our results with the prediction of other models is provided. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review D American Physical Society (APS)
