Testing chiral anomalies with hadronic currents
Chiral anomalies are calculated using an effective-Lagrangian technique introduced for anomalies by Wess and Zumino and recently reformulated by Witten. Anomalous amplitudes for vector currents decaying into three pseudoscalars are tested by comparison with K/sub l/4 decay, eta and eta'..--> pi../sup +/..pi../sup -/..gamma.., and strong decays of vector mesons. The agreement with experiment for K/sub l/4 is an impressive verification of the anomaly in the vector current. For eta and eta' decay, the results are excellent, and for the strong decays, good. Since the electromagnetic and strong amplitudes have been extrapolated to higher momenta with a final-state-interaction approximation, it is not surprising that the agreement is less good here, where, indeed, further dynamical assumptions are needed. A number of new predictions are made for hadronic decays of rho', ..omega..', and phi'.
