B→ρB\toρ, K∗K^* transition form factors in AdS/QCD model

preprint2014arXivOpen access

Abstract

We use the AdS/QCD distribution amplitudes for light mesons to calculate the transition form factors for B to ρρ, K∗K^* decays. These form factors are then utilized to make predictions for the semileptonic B→ρℓνB\toρ\ellν and dileptonic B→K∗μ+μ−B\to K^* μ^+μ^- decays. We compare our predictions to the experimental data from BaBar and LHCb.
