Description
The τ polarization asymmetry in τ→a1ν→π+-π0π0ν 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
