A TEST OF QUANTUM ELECTRODYNAMICS IN THE REACTION E+E- -]GAMMA-GAMMA(GAMMA)
We have measured the total and differential cross sections of the reaction e+e- → γγ(γ) at center-of-mass energies around 91 GeV, with an integrated luminosity of 14.2 pb-1. The results are in good agreement with QED predictions. We set lower limits, at 95% confidence level, on the QED cutoff parame...
