Abstract

A charge asymmetry has been observed in final-state jets from $e^{+}$ $e^{-}$ annihilation into hadrons at √s =29 GeV. The measured asymmetry is consistent with the prediction of electroweak theory. The product of axial-vector weak coupling constants, averaged over all quark flavors, is determined to be 〈 $g_{A}^{e}$ $g_{A}^{q}$ 〉=-0.34±0.06±0.05.
