Study of multiphoton final states and tests of QED in e+e− collisions at √s up to 209 GeV

The process e+e− → nγ with n 2 is studied at centre-of-mass energies ranging from √s = 192 to 209 GeV. The data sample corresponds to a total integrated luminosity of 427 pb−1. The total and differential cross sections are found to be in agreement with the QED expectations. Using all the data collec...

description The process e+e− → nγ with n 2 is studied at centre-of-mass energies ranging from √s = 192 to 209 GeV. The data sample corresponds to a total integrated luminosity of 427 pb−1. The total and differential cross sections are found to be in agreement with the QED expectations. Using all the data collected with the L3 detector above the Z pole, limits on deviations from QED, excited electrons, contact interactions, extra space dimensions and excited spin-3/2 leptons are set.
