Radiative Leptonic Decays of the charged $B$ and $D$ Mesons Including Long-Distance Contribution

Abstract

In this work we study the radiative leptonic decays of $B^{-}$, $D^{-}$ and $D_s^{-}\to \gamma l\bar{\nu }$, including both the short-distance and long-distance contributions. The short-distance contribution is calculated by using the relativistic quark model, where the bound state wave function we used is that obtained in the relativistic potential model. The long-distance contribution is estimated by using vector meson dominance model.
