description

Data taking around the Z resonance at LEP I ended in 1995, and determinations of the mass, width, hadronic pole cross section and leptonic couplings of the Z boson are approaching a final status. This is accompanied by an improved understanding of the beam energy during the high-statistics data taking approximately two GeV above and below the Z resonance in 1993 and 1995. Together with other precision measurements presented at this conference impressive tests of the consistency of the Standard Model can be made and an upper limit on the mass of the Higgs boson can be derived.
