摘要：

Quark-condensate contributions to triangle amplitudes arising from the nonperturbative content of the QCD vacuum are shown to uphold the anomalous axial Ward identity to leading and next-to-leading order in both the expansion parameter [m(quark)/momentum]2, as well as in the expansion parameter [m(pi)/m(quark]2 appropriate for pi0-gammagamma kinematics.
