Effect of the Charged Higgs Bosons in the Radiative Leptonic Decays of $B^{-}$ and $D^{-}$ Mesons

Ji-Chong Yang, Mao-Zhi Yang

In this work, we study the radiative leptonic decays of $B^{-}$ and $D^{-}$ mesons in the standard model and the two-Higgs-doublet-model type II. The results are obtained using the fac…
