TL;DR: The first physics runs of the L3 detector at LEP were reported in this article, where the authors determined the mass m z 0 and the width Γ z 0 of the intermediate vector boson Z 0 to bem z 0 =91.132±0.057 GeV (not including the 46 MeV LEP machine energy uncertainty).

TL;DR: In this article, the L3 muon spectrometer was used to achieve a momentum resolution Δp p = 2% at p = 45 GeV/c, where p is the number of particles in the detector.
Abstract: The L3 muon spectrometer is presented. Characteristics, useful for experiments at future accelerators, are highlighted. Particular emphasis is given to the systems envisaged to keep the error on the relative alignment of detectors below 30 μm and so reach a momentum resolution Δp p = 2% at p = 45 GeV/c. © 1989.
