Abstract
We consider various contributions to the nonresonant decay →, both of the long-distance and short-distance types, with the former providing for most of the branching ratio, predicted to be scrB(→)=(1.0–5.0)×. We also discuss an application to CP violation resulting from the interference of that nonresonant background [with m()≊3.4 GeV] and → followed by →. The resulting value of the partial rate asymmetry is (0.44–0.49)sinγ, where γ=arg().
