Resonance background to the decays b→sl+l, B→K/emph>l+l, and B→Kl+l

Abstract
We consider background to the rare decay modes b→sl+ l, B→K* l+ l, and B→Kl+ l arising from the process b→sVi followed by on- and off-resonance transition Vil+ l. We obtain dilepton mass spectrum including short-distance effects and then suggest cuts to enhance the signal over background.
