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 $K^*$, which cannot be seen in $e^++e^-$, should be observed in the $ K^- \pi^+ \pi^-$ decay channel.
