| Popis: | Measurements of the cross section for the muon-pair-annihilation reaction e/sup +/e/sup -/ ..-->.. ..mu../sup +/..mu../sup -/, relative to Bhabha scattering at 4/sup 0/, are reported at center-of-mass energies in the range 6.2--7.4 GeV. These measurements provide a fundamental test of quantum electrodynamics (QED) for timelike values of the invariant four-momentum transfer q/sup 2/ as high as 54.8 (GeV/c)/sup 2/, which in this reaction is carried by the photon propagator. The results are in agreement with predictions of QED. |
