THE PRODUCTION AND DECAY OF TAU-LEPTONS IN E+E- ANNIHILATION AT PETRA ENERGIES

THE PRODUCTION AND DECAY OF TAU-LEPTONS IN E+E- ANNIHILATION AT PETRA ENERGIES

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)-...
