The contribution of the J/psi resonance to the radiative B decays

Abstract

The radiative decays of the B mesons may have a significant contribution from the transition b -> s J/psi followed by the J/psi-photon conversion. The size of this contribution is re-analysed in the light of a phenomenological model for the weak bsJ/psi vertex, and a modified J/psi-photon interaction that is manifestly gauge invariant. Predictions for both inclusive and exclusive cases are obtained, but large uncertainties still remain.
