Examination of the Resonance Contributions to Dileptonic Rare B-Decays

Abstract

We analyse the long-distance contribution to $B\to X_s{\ell }^{+}{\ell }^{-}$ differential decay rate when the momentum dependence of $\psi$ and ${\psi }^{\prime }$-$\gamma$ conversion strength is taken into account. The results indicate that the resonance to nonresonance interference in the dilepton invariant mass distribution is substantially reduced.
