Abstract

Differential cross sections for the reactions e+e- → e+e- and e+e- → γγ are given for energies between 27.7 and 31.6 GeV. The results agree with the predictions of standard quantum electrodynamics and set lower limits to the usual cut-off parameters of up to 104 GeV. A limit on the Weinberg angle, sin2θW < 0.63, is obtained at unprecedentedly high q2.
