A bstractWe present Bq → ρ, Bq → ω, Bq → K∗, Bs → K∗ and Bs → ϕ form factors from light-cone sum rules (LCSR) at Oαs$$\mathcal{O}\left({\alpha}_s\right)$$ for twist-2 and 3 and Oαs0$$\mathcal{O}\left({\alpha}_s^0\right)$$ for twist-4 with updated hadronic input parameters. Three asymptotic light-cone distribution amplitudes of twist-4 (and 5) are determined, necessary for the form factors to obey the equations of motion. It is argued that the latter constrain the uncertainty of tensor-to… Expand
