QED Test at LEP200 Energies in the Reaction $e^{+}e^{-} \to \gamma\gamma(\gamma)$
The measurements of the QED reaction $\EEGG$ performed with the L3 detector are used to search for new physics phenomena beyond the Standard Model. No evidence for these phenomena is found and new limits on their parameters are set. First the reaction is used to constrain a model of an excited elect...
