Abstract.

We have carried out a precision measurement of the parity-violating asymmetry A PV in the scattering of longitudinally polarized electrons off electrons in a liquid-hydrogen target. The measurement was performed with the 50GeV beam line at SLAC. The final result with the full data set collected in three production runs is A PV = - 131±14 (stat) ±10 (syst) parts per billion. The result leads to new limits on possible contact interactions at the TeV scale. We discuss future prospects for more precise measurements.
