Measurement of the τ Polarization Asymmetry in τ→a1 v→π±π0π0v Decay at Z0 Peak

Abstract: The τ polarization asymmetry in τ→a1v→π±π0 π0v decay at Z0 peak is measured using data collected by L3 detector at LEP in 1992 and 1993, Apol=-0.239±0.126±0.100, where the first error is statistical and the second systematic. And the effective electroweak mixing angle sin2θw=0.2197±0.0219 is derived.
