Abstract

A high-statistics measurement has been made of the process e+e-+- at s=29 GeV with the MAC detector at the SLAC storage ring PEP. The electroweak forward-backward charge asymmetry for a sample of approximately 16 000 events was measured to be A=-0.0630.0080.002. The ratio of the cross section to the lowest-order QED cross section was measured to be R=1.010.010.03. From these results the weak neutral axial-vector and vector couplings are determined to be gAegA=0.250.030.01 and gVegV=-0.020.030.09. © 1985 The American Physical Society.
