The Mark J Collaboration at the DESY $e^{+}$ $e^{-}$ collider PETRA presents results on the electroweak reactions $e^{+}$ $e^{-}$ → $μ^{+}$ $μ^{-}$ $τ^{+}$ $τ^{-}$ , $μ^{+}$ $μ^{-}$ γ, and $e^{+}$ $e^{-}$ $μ^{+}$ $μ^{-}$ . The c.m. energy range is 12 to 46.78 GeV. In the $μ^{+}$ $μ^{-}$ and $τ^{+}$ $τ^{-}$ channels the total cross sections and the forward-backward asymmetries are reported and compared with other experiments. The results are in excellent agreement with the standard model. The weak-neutral-current vector and axial-vector coupling constants are determined. The values for muons and τ’s are compatible with universality and with the predictions of the standard model. In the $μ^{+}$ $μ^{-}$ γ channel, all measured distributions, including the forward-backward muon asymmetry, are in excellent agreement with the electroweak theory. Our data on the two-photon process, $e^{+}$ $e^{-}$ $μ^{+}$ $μ^{-}$ , agrees with QED to order $α^{4}$ over the entire energy range and the $Q^{2}$ range from 0.7 to 166 ${GeV}^{2}$ .
