Polarization and Handedness in Tau -> 3 Pi + Neutrino Decay Produced in e+e- Annihilations

N. A. Tornqvist

We discuss the concept of handedness applied to $\tau$ production in $e^{+}{e}^{-}$ annihilations with $\tau$ decaying into $a_1{\nu }_{\tau }\to 3\pi {\nu }_{\tau }$. The $a_1\to 3\pi$ decay is particularly interesting…
