Electroweak precision measurement with leptons
- SLAC
The precision measurements of lepton electroweak parameters at SLD and LEP are reviewed and discussed. The updated SLD weak mixing angle measurement from ALR and the lepton left-right forward-backward asymmetries is sin{sup 2} {theta}{sup eff}/W = 0.23099 {+-} 0.00026, and the combined SLD/LEP lepton-based value is 0.23119 {+-} 0.00020. This value differs by over 3{sigma} from the comparable quark-based value.
