The radiative decays of the B mesons may have a significant contribution from the transition b→sJ/ψ followed by the J/ψ-photon conversion. The size of this contribution is reanalyzed in the light of a phenomenological model for the weak bsJ/ψ vertex, and a modified J/ψ-photon interaction that is manifestly gauge invariant. Predictions for both inclusive and exclusive cases are obtained, but large uncertainties still remain. © 1995 The American Physical Society.
