Measurement of the Reaction $e^+ e^- \to \mu^+ \mu^-$ for 14-{GeV} $\le \sqrt{s} \le$ 36.4-{GeV}

. The total cross section result is in good agreement with the QED prediction and the following Λ values have been obtained:Λ+=186 GeV,Λ−=101 GeV. The angular distribution at high energy (

\left( {\left. {\left\langle {\sqrt S } \right.} \right\rangle= 34.2 GeV} \right)

) shows a fitted charge asymmetry of −0.064±0.064 in agreement with theW-S model prediction of −0.092, corresponding to an axial coupling parametera2=4ga2=0.69±0.69.
