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
