摘要

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 $B\ra X_s J/\Psi (\Psi^{\prime}) \ra X_s e^+ e^-$ . We find that the resonance to nonresonance interference are reduced substantially.
