We study the rare radiative dileptonic decays B0( Bs) →γe+e- (e = 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 Bs →γμ+μ-,γe+e-,and 10-10 for Bo →γμ+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(Bs) wave function.
