The cross-sections and the forward-backward charge asymmetries of muon and tau pairs produced ine+e− collisions at$\sqrt s= 35 GeV$ have been measured by the JADE Collaboration. The cross-sections,$\sigma _\mu(\sqrt s= GeV) = 69.79 \pm 1.35 \pm 1.40 pb$ and$\sigma _\mu(\sqrt s= GeV) = 71.72 \pm 1.48 \pm 1.61 pb$, are in agreement with the QED α3 prediction. The charge asymmetries areAμ=−(9.9±1.5±0.5)% andAτ=−(8.1±2.0±0.6)% in agreement with the value −9.2% predicted by the standard model, usingMZ=91.0 GeV and sin2θW=0.230.
