Spin analysis of the process $e^{+}e^{-}\rightarrow\tau^{+}\tau^{-}$ at LEP
Using the data collected by the four experiments at LEP during 1990-1994, a precise measurement of the tau longitudinal polarisation (P_tau) has been performed, as well as the measurement of the transverse-transverse and transverse-normal tau spin correlations. From the P_tau measurement, assuming l...

| description | Using the data collected by the four experiments at LEP during 1990-1994, a precise measurement of the tau longitudinal polarisation (P_tau) has been performed, as well as the measurement of the transverse-transverse and transverse-normal tau spin correlations. From the P_tau measurement, assuming lepton universality of the neutral currents, the effective weak mixing angle has been determined to be sin(theta_W) = 0.2325 +- 0.0006. The Standard Model predictions are consistent with the measured results. |
