Abstract
The measurement of the nonelectromagnetic forward-backward charge asymmetry in the reaction at GeV and in the angular region is reported. With a systematic error less than 1%, we observe an asymmetry of (-8.1±2.1)%. This is in agreement with the standard electroweak theory prediction of (-7.6±0.6)%. The weak-current coupling constants are also reported.
