We present results for rare radiative leptonic B-decays We calculate non-perturbative QCD part via relativistic quark model, which is a dispersion approach based on the constituent quark picture. We include the long-distance contribution, represented by light and vector resonances, as an additional effective term to the Wilson coefficient C9. We give predictions for the branching ratios, as well as distributions of the differential rates and the forward-backward asymmetry. Finally, we consider experimental limits on the Wilson coefficient C7γ and the corresponding sensitivity of the zero-point of the forward-backward asymmetry.
