Abstract

The CP-violating asymmetry [Γ(

→

π^{+}

π^{+}

π^{-}

) -Γ(

→

π^{-}

π^{-}

π^{+}

)]/[Γ (

π^{-}

)+Γ(

)] is determined by CP violation in kaon decay amplitudes. We derive an expression for this asymmetry in the standard six-quark model including CP violation from both strong and electromagnetic penguin-type diagrams.
