INTERPOLATING AXIAL ANOMALY INDUCED AMPLITUDES

We propose to use quark triangle anomaly graph amplitudes with QCD corrections as an interpolating formula for the amplitude induced by the axial anomaly. The QCD corrections to this amplitude are generally described by two major contributions coming from the qqBAR bound state and the background continuous spectrum, respectively. For the first contribution, we include the contributions of the lowest vector bound state, and the second contributions comes from the quark triangle graph with a QCD corrected constituent masses used for the internal quark lines. Using the resulting form factor, we fit the experimental data for the pi0gamma and the omegapi0 transition form factors and show that our result describes the experimental data well.
