Abstract

Light front Holography is a formalism developed by Brodsky and de T\'{e}ramond in which analytic forms for the hadronic bound state wavefunctions can be obtained. We have used the holographic light front wavefunctions thus obtained in order to calculate the distribution amplitudes of the light vector mesons $\rho$ and $K^*$. As a result, we are able to calculate the form factors for $B\to \rho , K^*$ transitions as well as $\Lambda_{\rm QCD}/m_b$ contributions in radiative $B_{(s)}\to (\rho ,K^*)\gamma$ decays. We compare our predictions to the available experimental data.
