| dc.description | We consider the effect of new physics interactions in the form of tensor operators on the branching ratio of B_s --> l+ l- gamma where l=e, mu. We find that the present data on the inclusive branching ratio B --> X_s l+ l- puts a strong constraint on the new physics tensor couplings and does not allow a large enhancement in the branching ratio of B_s --> l+ l- gamma beyond its standard model predictions. Large enhancement in the branching ratio of B_s --> l+ l- gamma due to new physics in the form of vector/axial-vector, scalar/pseudoscalar and magnetic dipole operators has already been ruled out. Thus we conclude that no new physics can provide a large enhancement in the branching ratio of B_s --> l+ l- gamma and hence it is expected to be observed in future experiments with a branching ratio close to its standard model expectation. | |
