Tau mesonic decays and strong anomaly of PCAC

Abstract

Strong anomaly of the PCAC is found in $\tau \to \omega \pi \pi \nu$ and $\omega \rho \nu$ in the chiral limit. It originates in WZW anomaly. Theoretical result of $\tau \to \omega \pi \pi \nu$ agrees with data well and the measurement of $\tau \to \omega \rho \nu$ will confirm the strong anomaly of PCAC. The strong anomaly of PCAC is studied.
