摘要
We evaluate the rare decays Bs→γе＋е in the standard model, considering the off-shell effect of quarks in Bs meson as well as some contributions neglected in previous works. It is found that the quarks off-shell are large. With the predicted branching ratios at order of 10-s, it is expected that the radiative dileptonic decays will be detected in the LHC-b experiments.
