Experimental study of the reactions e+e--->e+e- and e+e---> gamma gamma at 29 GeV.

Abstract:

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 -cos...
