摘要：

We use QCD light-cone sum rules with holographic anti-de Sitter/Chromodynamics ( AdS/QCD) distribution amplitudes for the K* meson in order to predict the full set of seven B -> 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, B -> K*mu(+)mu(-), which we compare to the recent LHCb data.
