Abstract An analysis of the three leptonic reactionse+e&#8722;&#8594;e+e&#8722;,&#956;+&#956;&#8722; and&#964;+&#964;&#8722; over a wide range of energy, $12< \sqrt s< 46.78 GeV$ is presented. The data were obtained with the JADE detector at thee+e&#8722; storage ring PETRA. They are compared to predictions of electroweak theories, in particular the standard model. For the total cross-sections of all three reactions and for the differential cross-section of Bhabha scattering no deviation from QED is found over the entire energy range. The differential cross-sections of &#956; and &#964; pairs at high energies show the angular asymmetry predicted by electroweak interference. The axial-vector and vector weak coupling constant, sin2&#952;W andMZ are determined and compared to other measurements. Finally, limits on deviations from the standard model are given.
