THE REACTION E+E--] GAMMA-GAMMA(GAMMA) AT Z0 ENERGIES
The total and differential cross-sections for the reaction e+e- –> gamma-gamma(gamma) are measured at centre of mass energies around 91 GeV using an integrated luminosity of 4.7 pb-1. The agreement with the QED prediction is good. Consequently there is no evidence for non-standard channels which would have the same experimental signature. The lower limits on the QED cutoff parameters are LAMBDA+ > 113 GeV and LAMBDA- > 95 GeV. An upper limit on the effective coupling between a possible excited electron and the gamma is derived. At 95% confidence level the branching ratios for Z0 decay into pi-0-gamma, eta-gamma and gamma-gamma-gamma are below 1.5 x 10(-4), 2.8 x 10(-4) and 1.4 x 10(-4) respectively.
