Spin analysis of the process e{sup +}e{sup -}{yields}{tau}{sup +}{tau}{sup -} at LEP

Abstract

Using the data collected by the four experiments at LEP during 1990-1994, a precise measurement of the {tau} longitudinal polarisation (P{sub {tau}}) has been performed, as well as the measurement of the transverse-transverse (C{sub TT}) and transverse-normal (C{sub TN}) {tau} spin correlations. From the P{sub {tau}} measurement, assuming lepton universality of the neutral currents, the effective weak mixing angle has been determined to be sin{sup 2}{theta}{sub W}=0.2325{+-}0.0006. The measured results are consistent with the standard model predictions. (orig.). 10 refs.
