Abstract Using the Bs meson wave function extracted from non-leptonic Bs decays, we evaluate the rare decays Bs→?+?? γ(?=e,μ) in the standard model, including contributions from all four kinds of diagrams. We focus on the contribution from the four-quark operators, which were not taken into account properly in previous studies. We find that the contribution is large, leading to the branching of Bs→?+??γ being nearly enhanced by a factor 3 and up to 1.6×10?8. The predictions for such processes can be tested in the LHC-b and B factories in the near future.
