Abstract

The reactions

e^{+} e^{-} \to e^{+} e^{-}

and

e^{+} e^{-} \to μ^{+} μ^{-}

have been measured at center-of-mass energies 3.0, 3.8, and 4.8 GeV and production angles of

50 ° < θ < 130 °

over all azimuthal angles. Agreement with quantum electrodynamics is excellent. New limits for cutoff parameters in quantum-electrodynamic-breakdown models are given.
