MEASUREMENT OF THE E+E- -] GAMMA-GAMMA(GAMMA) CROSS-SECTION AT LEP ENERGIES
The total and the differential cross sections for the reaction e+e- → γγ(γ) have been measured with the DELPHI detector at LEP using an integrated luminosity of 36.9 pb-1. The results agree with the QED predictions and consequently there is no evidence for non-standard channels with the same experim...
