Measurements of Four-Fermion Production via Neutral Elektroweak Currents at LEP

Four-fermion production via electroweak neutral currents has been measured by all four LEP collaborations at center-of-mass energies near the Z resonance and for the first time also at energies well above the Z peak. Essentially all possible final states have been covered in four different topologies.
