Abstract

The form factors of semileptonic B(s)a1(K1)+, =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.
