Measurement of the reactione + e −→μ + μ − for\(14 \leqq \sqrt S \leqq 36.4\) GeV

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

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 parametera 2=4g 2 a =0.69±0.69.
