Measuring the Wess-Zumino Anomaly in Tau Decays

Abstract

We propose to measure the Wess-Zumino anomaly contribution by considering angular distributions in the decays $\tau \to {\nu }_{\tau }\eta {\pi }^{-}{\pi }^0$, $\tau \to {\nu }_{\tau }{K}^{-}{\pi }^{-}{K}^{+}$ and $\tau \to {\nu }_{\tau }{K}^{-}{\pi }^{-}{\pi }^{+}$. Radial excitations of the $K^{\ast }$, which cannot be seen in $e^{+}+e^{-}$, should be observed in the $K^{-}{\pi }^{+}{\pi }^{-}$ decay channel.
