摘要

The Mark J Collaboration at the DESY e+e- collider PETRA presents results on the electroweak reactions e+e-+-+-,+-, and e+e-+-. The c.m. energy range is 12 to 46.78 GeV. In the +- and +- 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 s are compatible with universality and with the predictions of the standard model. In the +- 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-+-, agrees with QED to order ±4 over the entire energy range and the Q2 range from 0.7 to 166 GeV2.
