Description
We study the rare radiative dileptonic decays $B^0(B_s)\to γ\ell^+\ell^-$ ($\ell=e,μ$) in the standard model. By using the $B$ meson wave function constrained by non-leptonic decays, the branching ratios turn out to be of the order of $10^{-9}$ for $B_s\toγμ^+μ^-$, $γe^+ e^-$ and $10^{-10}$ for $B^0\toγμ^+μ^-$, $γe^+ e^-$. Based on the study, these decays are accessible at the near future LHC-b experiment, which are useful to determine the $B(B_s)$ wave function.
