The reaction (e+e−→μ+μ−) has been measured between$\sqrt S = 14.0$ and$\sqrt S = 36.4$. 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=4g a 2=0.69±0.69.
