$B\to \rho$, $K^{\ast }$ transition form factors in AdS/QCD model

We use the AdS/QCD distribution amplitudes for light mesons to calculate the transition form factors for B to $\rho$, $K^{\ast }$ decays. These form factors are then utilized to make predictions for the semileptonic $B\to \rho \mathrm{\ell }\nu$ and dileptonic $B\to K^{\ast }{\mu }^{+}{\mu }^{-}$ decays. We compare our predictions to the experimental data from BaBar and LHCb.
