Measurement of the tau lepton polarisation at LEP2

A first measurement of the average polarisation Pτ of tau leptons produced in e+e- annihilation at energies significantly above the Z resonance is presented. The polarisation is determined from the kinematic spectra of tau hadronic decays. The measured value Pτ = - 0.164 ± 0.125 is consistent with t...
