Reexamination of the resonance contributions in B->X_s e^+ e^-

Abstract

With help of the recent developments in the heavy quarkonium physics, we reexamine the long distance(LD) effects in \Bsee dominantly from the charmonium resonances $J/\Psi$ and ${\Psi }^{\prime }$ through the decay chains $B\ra X_s J/Ψ(Ψ^{\prime}) \ra X_s e^+ e^-$. We find that the resonance to nonresonance interference are reduced substantially.
