Abstract

We have studied 419 τ pair events produced in the reaction e⁺e^-→τ⁺ τ^- at a c.m. energy of 34.6 GeV. We measure the cross section and angular distribution, as well as the decay branching ratios. The production characteristics are consistent with the Standard Electroweak Model predictions of γ and Z⁰ interference. The branching ratios are generally consistent with the τ decaying according to standard weak interaction principles, but we observe somewhat more decays resulting in single charged hadrons plus neutrals than are predicted by present theory.

The production characteristics are consistent with the Standard Electroweak Model predictions of γ and Z0 interference.
