Abstract

We report measurements of $e^{+} e^{-} \to e^{+} e^{-}$ , $e^{+} e^{-} \to γ γ$ , and $e^{+} e^{-} \to μ^{+} μ^{-}$ at angles close to 90°, relative to Bhabha scattering at 3.7°, at a center-of-mass energy equal to 5.2 GeV. The results are found to be consistent with the predictions of quantum electro-dynamics.
