An Improved Direct Measurement of Leptonic Coupling Asymmetries with Polarized
We report new direct measurements of the Z 0-lepton coupling asymmetry parameters Ae, Aµ and Aτ , with polarized Z 0 's collected by the SLD detector at the SLAC Linear Collider. The parameters are extracted from the measurement of the left-right-forward-backward asymmetries for each lepton species.

متن کاملDirect Measurement of Leptonic Coupling Asymmetries with Polarized Z's * the Sld Collaboration
We present direct measurements of the Z 0-lepton coupling asymmetry parameters, A e , A µ , and A τ , based on a data sample of 12,063 leptonic Z 0 decays collected by the SLD detector. The Z bosons are produced in collisions of beams of polarized e − with unpolarized e + at the SLAC Linear Collider. The couplings are extracted from the measurement of the left-right and forward-backward asymmet...

We report new direct measurements of the Z-lepton coupling asymmetry parameters Ae, A and A , with polarized Z 's collected by the SLD detector at the SLAC Linear Collider. The parameters are extracted from the measurement of the left-right-forward-backward asymmetries for each lepton species. The 1996, 1997 and 1998 SLD runs are included in this analysis and combined with published data from t...

We present final measurements of the Z boson-lepton coupling asymmetry parameters Ae, Aμ, and Aτ with the complete sample of polarized Z bosons collected by the SLD detector at the SLAC Linear Collider. From the leftright production and decay polar angle asymmetries in leptonic Z decays we measure Ae = 0.1544 ± 0.0060, Aμ = 0.142 ± 0.015, and Aτ = 0.136 ± 0.015. Combined with our left-right asy...
