Reexamination of the resonance contributions in B→Xse+e−

With the help of the recent developments in the heavy quarkonium physics, we reexamine the long distance (LD) effects in B→Xse+e− dominantly from the charmonium resonances J/Ψ and Ψ′ through the decay chains B→XsJ/Ψ(Ψ′)→Xse+e−. We find that the resonance to nonresonance interference are reduced substantially.
