Abstract

The radiative dileptonic decays B-s(B-d)-->l(+)l(-)gamma (l=e,mu) are investigated within the standard model. The transition form factors are calculated in the framework of the light cone QCD sum rule method and it is found that the branching ratios are B(B-s-->e(+)e(-)gamma) = 2.35 x 10(-9), B(B-s-->mu(+)mu(-)gamma) = 1.9 x 10(-9) B(B-d-->e(+)e(-)gamma) = 1.5 x 10(-10), and B(B-d-->mu(+)mu(-)gamma) = 1.2 x 10(-10). A comparison of our results with the constituent quark model predictions on the branching ratios is presented.
