TL;DR: The L3 experiment as discussed by the authors is one of the six large detectors designed for the new generation of electron-positron accelerators, which is the only detector that concentrates its efforts on limited goals of measuring electrons, muons and photons.

TL;DR: In this article, the design and construction of the silicon strip microvertex detector (SMD) of the L3 experiment at LEP are described and the sensors, readout electronics, data acquisition system, mechanical assembly and support, displacement monitoring systems and radiation monitoring system of the recently installed double-sided, double-layered SMD.

TL;DR: In this paper, the absolute muon flux between 20 and 3000 GeV was measured with the L3 magnetic muon spectrometer for zenith angles ranging from 0°to 58°.

TL;DR: In this article, the authors present a study of the inclusive production of neutral pions and charged particles from 112 000 hadronic Z 0 decays and compare their results to e + e − data between √ s = 9 and 91 GeV.

TL;DR: In this article, a search for the neutral Higgs boson using the processes Z 0 → H 0 e + e −, Z0 → H ε + ε, Z ε → H τ + τ −, Zε → ε v v, and Z 0→ H 0 q q q, is performed on data collected by the ALEPH detector corresponding to about 11 550 events of Z0→ hadrons.
