Abstract
We consider various contributions to the nonresonant decay B±→π+π-π±, both of the long-distance and short-distance types, with the former providing for most of the branching ratio, predicted to be scrB(B±→π+π-π±)=(1.0-5.0)×10-5. We also discuss an application to CP violation resulting from the interference of that nonresonant background [with m(π+π-)3.4 GeV] and B±→χc0π± followed by χc0→π+π-. The resulting value of the partial rate asymmetry is (0.44-0.49)sinγ, where γ=arg(Vub*). © 1995 The American Physical Society.
