Abstract
A low-energy theorem relating to is derived by using anomalous Ward identities and by using Schwinger's proper-time technique. We discuss the theoretical significance of this low-energy theorem. In particular, the theorem is meaningful only if the partially conserved axial-vector current anomaly is in fact responsible for the decay .
