Abstract

Production of events with multihadronic and leptonic final states has been measured in e +e − collisions at centre-of-mass energies significantly above the Z 0 mass, using the OPAL detector at LEP. A substantial production rate of radiative Z 0γ events was observed, as expected, together with events with less energetic initial-state photons. The cross-sections and leptonic forward-backward asymmetries were measured and compared with Standard Model expectations. In a model-independent fit to the Z 0 lineshape, the hadronic cross-section and lepton asymmetries presented here provide constraints on the size of the γZ 0-interference term which are complementary to those afforded by LEP data accumulated at the Z 0 resonance.
