TESTS OF QED WITH MULTI-PHOTONIC FINAL STATES
/ Authors
/ Abstract
In the Standard Model the process e+e- -> gamma-gamma is fully described by QED. Measurements of the differential cross-sections from the four LEP experiments are compared to the QED expectation and limits are set on parameters describing physics beyond the Standard Model. Three-photon events are used for a direct search for a photonically decaying resonance produced together with a photon.
