英文摘要Hadron production and lepton-pair production in e(+)e(-) collisions are studied with data collected with the L3 detector at LEP at centre-of-mass energies root s = 192-208 GeV. Using a total integrated luminosity of 453 pb(-1), 36057 hadronic events and 12863 lepton-pair events are selected. The cross sections for hadron production and lepton-pair production are measured for the full sample and for events where no high-energy initial-state-radiation photon is emitted prior to the collisions. Lepton-pair events are further investigated and forward-backward asymmetries are measured. Finally, the differential cross sections for electron-positron pair-production is determined as a function of the scattering angle. An overall good agreement is found with Standard Model predictions.
