Abstract: (APS)
The angular distributions of the process e+e−→e+e− measured by the Bologna-CERN-Frascati group at the electron-positron colliding-beam facility Adone are analyzed in terms of standard quantum electrodynamics (QED) to order α3 including soft- and hard-photon emission. An analytical expression is given for the cross section of the process e+e−→e+e−γ for hard photons. Detailed numerical results for that specific experimental setup are obtained by a Monte Carlo program. It is found that this bremsstrahlung process is responsible for the noncollinear and noncoplanar events observed at Frascati. Therefore, these data, together with the present calculation, provide a test of QED for this particular physical situation involving high energies and large momentum transfers.
