An analysis of the three leptonic reactions e+e-→e+e-, μ+μ- and τ+τ- over a wide range of energy, {Mathematical expression} is presented. The data were obtained with the JADE detector at the e+e- 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 μ and τ pairs at high energies show the angular asymmetry predicted by electroweak interference. The axial-vector and vector weak coupling constant, sin2θW and MZ are determined and compared to other measurements. Finally, limits on deviations from the standard model are given.
