Abstract

Off-mass-shell effects in $ω \to 3 π$ decay are discussed in the context of hard-pion current-algebra technique. Anomalous Ward identities are used instead of the naive ones. The decay amplitude depends upon $ξ$ , which characterizes the contact term, and $δ$ , the parameter appearing in the $A_{1 ρ π}$ system. Results for $Γ (ω \to 3 π)$ for $δ = 0$ to $δ = - 1$ are presented.
