B_{d,s}->rho, omega, K*, phi Decay Form Factors from Light-Cone Sum Rules Revisited

Abstract

We present an improved calculation of $B\to$ light vector form factors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading order twist-4 corrections. The total theoretical uncertainty of our results at zero momentum transfer is typically 10% and can be improved, at least in part, by reducing the uncertainty of hadronic input parameters. We present our results in a way which details the dependence of the form factors on these parameters and facilitates the incorporation of future updates of their values from e.g. lattice calculations. We also give simple and easy-to-inplement parametrizations of the $q^2$-dependence of the form factors which are valid in the full kinematical regime of $q^2$.
