Abstract

The polarization of τ leptons in the reaction e⁺e^- → τ⁺τ^- has been measured using a e⁺e^- collider, TRISTAN, at the center-of-mass energy of 58 GeV. From the kinematical distributions of daughter particles in τ → eνν̄, μνν̄, ρν or π(K)ν decays, the average polarization of τ^- and its forward-backward asymmetry have been evaluated to be 0.012±0.058 and 0.029±0.057, respectively.
