Tau polarization measurements using the pion and the lepton channels

Research output: Contribution to journalArticlepeer-review

Abstract

The measurements of the average τ-polarization, (Pτ), and its forward-backward asymmetry, Apol FB, at LEP using the decay channels τ→eν-eντ, τ→μν-μντ and τ → π(K)ντ are presented. The experimental methods used to extract the polarization and estimate the systematic uncertainties are elaborated. By the end of 1995, the overall errors are expected to decrease by almost a factor of two.
