Abstract

The differential cross section of the reaction e⁺e^-→e⁺e^- at a c.m. energy of 34.7 GeV has been measured. The result, together with our previously measured e⁺e^-→α⁺α^- data, are compared with the standard model predictions. We obtain for the weak neutral current couplings the values g_v²=0.09×0.06, g_a²=0.38×0.08. A fit of the Weinberg mixing angle gives the value g_v²=0.09×0.06, g_a²=0.038×0.08. The data are also used to set limits on possible deviations from the pointlike structure of leptons. An upper limit for the e⁺e^- coupling to a heavy spin 0 boson is also given.
