This paper reports measurements of the differential cross sections for the reactions e+e-'e+e- (Bhabha scattering) and e+e-' (-pair production). The reactions are studied at a center-of-mass energy of 29 GeV and in the polar-angular region -costheta -<0.55. A direct cross-section comparison between these two reactions provides a sensitive test of the predictions of quantum electrodynamics (QED) to order ±3. When the ratio of -pair to Bhabha experimental cross sections, integrated over -costheta -<0.55, is divided by the same ratio predicted from ±3 QED theory, the result is 1.007±0.009±0.008. The 95%-confidence limits on the QED-cutoff parameters are +>154 GeV and ->220 GeV for Bhabha scattering, and +>59 GeV and ->59 GeV for -pair production. © 1986 The American Physical Society
