A study on the radiative dileptonic decays $B^0(B_s)\to \gamma {\ell }^{+}{\ell }^{-}$

Jun-Xiao Chen, Zhao-Yu Hou, Cai-Dian Lu

We study the rare radiative dileptonic decays $B^0(B_s)\to \gamma {\ell }^{+}{\ell }^{-}$ ($\ell =e,\mu$) in the standard model. By using the $B$ meson wave function constrained by non-leptonic decay…
