Predicting B->K* form factors in light-cone QCD

High Energy Physics - Phenomenology 2014-06-10 v1

Abstract

We use QCD light-cone sum rules with holographic anti de Sitter/Chromodynamics (AdS/QCD) Distribution Amplitudes (DAs) for the KK^* meson in order to predict the full set of seven BKB \to K^* transition form factors for intermediate-to-high recoil of the vector meson. We provide simple parametrizations for the form factors that fit our AdS/QCD predictions. We also provide parametrizations that fit both our AdS/QCD predictions and the most recent lattice data for low recoil. We use our form factors to predict the differential and total branching fraction of the rare dileptonic decay BKμ+μB \to K^* \mu^+ \mu^- which we compare to the recent LHCb data.
