Abstract
We report on a precision measurement of the parity-violating asymmetry in fixed target electron-electron (Møller) scattering: APV=[−131±14(stat)±10(syst)]×10−9, leading to the determination of the weak mixing angle sin2θWeff=0.2397±0.0010(stat)±0.0008(syst), evaluated at Q2=0.026 GeV2. Combining this result with the measurements of sin2θWeff at the Z0 pole, the running of the weak mixing angle is observed with over 6σ significance. The measurement sets constraints on new physics effects at the TeV scale.
