Abstract

Cross sections for the reactions e⁺e^-→e⁺e^- (Bhabha scattering) and e⁺e^-→γγ are measured for center-of-mass (c.m.) energies {Mathematical expression} between 12.0 and 34.6 GeV. The results agree with the predictions of Quantum Electrodynamics (QED) and the cut-off parameters are determined. From Bhabha scattering at the highest energy, {Mathematical expression}, the 1 δ limits 0.12<sin² θ{symbol}_w<0.38 are obtained for the weak mixing angle. The higher order (α³) QED processes e⁺e^-→e⁺e^-γ and e⁺e^-→γγγ are also studied and are found to agree with the α³ QED predictions. A search for excited electrons is carried out by investigating the (e^±γ) invariant mass distribution in the reaction e⁺e^-→e⁺e^-γ.
