Tau mesonic decays and strong anomaly of PCAC
Bing An Li
Abstract
Strong anomaly of the PCAC is found in τ→ωππν and ωρν in the chiral limit. It originates in WZW anomaly. Theoretical result of τ→ωππν agrees with data well and the measurement of τ→ωρν will confirm the strong anomaly of PCAC. The strong anomaly of PCAC is studied.
