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/ΨJ/\Psi and Ψ′\Psi^{\prime} through the decay chains B\ra X_s J/\Psi (\Psi^{\prime}) \ra X_s e^+ e^-. We find that the resonance to nonresonance interference are reduced substantially.Comment: Revtex file,11 pages,1 figures,Phys.Lett.B in pres
