Abstract
The polarization of τ leptons produced in e+e- → τ+ τ-(γ) is measured using a sample of 8977 τ+ τ- pairs collected near the peak of the Z0 resonance. A polarization of −0.132±0.026(stat)±0.021(syst.) is determined. This corresponds to a ratio of the vector to the axial-vector coupling constants of the τ lepton to the weak neutral current of gV τ V /g τ Aeff = 0.067±0.017. This leads to a value of the effective sin2θw at the Z0 resonance of sin2θeff= 0.2326±0.0043.
