Abstract

The reactions e+e- → e+e-e+e- and e+e- → e+e-μ+μ-, in a single tag configuration, are studied at LEP with the L3 detector. The data set corresponds to an integrated luminosity of 93.7 pb-1 at √s = 91 GeV. Differential cross sections are measured for 1.4GeV2 ≤ Q2 ≤ 7.6 GeV2. The leptonic photon structure function Fγ 2 and azimuthal correlations are measured for e+e- → e+e-μ+μ-. The related structure functions Fγ A and Fγ B, which originate from interference terms of the scattering amplitudes, are determined for the first time.
