Abstract

We have observed τ pair production at average CM energies of 13.9, 22.3, 34.5 and 43.1 GeV. The cross-sections are consistent with QED, the cut off parameters being Λ₊>161 GeV and Λ_-169 GeV (95% CL). The topological branching fraction of the τ to 1 charged particle, B₁, is 0.847±0.011 (stat)_-0.013^+0.016(syst) and no decays to 5 charged particles were observed resulting in B₅-→π^-π⁺π^-v)/(B(τ^-→π^- π⁺π^-v)+B(τ^-→π^-π⁺π ^-π⁰v))=0.37_-0.20^+0.35
