Experience with the L3 vertex drift chamber at LEP
/ Anderhub, H ; Beissel, F ; Betev, B L ; Biland, A ; Böhm, A ; Bourilkov, D ; Camps, C ; Commichau, V ; Djambazov, L ; Göttlicher, P et al.
The vertex drift chamber of the L3 Experiment at LEP, based on the time expansion principle, was in operation from the start-up of LEP in 1989 until the shutdown of LEP in 2000. The gas mixture used was 80% CO//2 and 20% i-C//4H//1//0 at a pressure of 1200 mbar. [...]

Results on long-term performances and laboratory tests of the L3 RPC system at LEP
/ Alviggi, M G ; Carlino, G ; Conventi, F ; De Asmundis, R ; Della Pietra, M ; Della Volpe, D ; Patricelli, S ; Paolucci, P ; Piccolo, D ; Sciacca, C et al.
The RPC detectors in the L3 experiment at LEP work as a trigger system for the Forward-Backward Muon Spectrometer. It consists of 192 bi-gap RPCs working in streamer mode. [...]

Results of long-term performance and subsequent laboratory tests of RPCs of the L3 forward-backward muon spectrometer
/ Alviggi, M G ; Caprio, M A ; Carlino, G ; Conventi, F ; De Asmundis, R ; Della Pietra, M ; Della Volpe, D ; Iengo, P ; Paolucci, P ; Patricelli, S et al.
The RPC chambers in the L3 forward-backward muon spectrometer have been operational from 1994 to the end of LEP running. After dismantling of the L3 detector some of the RPCs modules have been transported to Napoli where their performance has been re-measured with cosmic rays. [...]

Quarks and gluons : tests of QCD in $e^{+}e^{-}$ annihilations
/ Duchesneau, D ; Field, J H ; Jeremie, H
This article gives an overview of the main experimental tests of perturbative QCD performed at LEP. It covers the following topics: determination of alpha /sub s/ from event shapes, tests of flavour independence of alpha /sub s/, studies of heavy quark mass effects, differences between quark and gluon jet fragmentation and study of the triple gluon vertex. [...]

Direct search for the standard model Higgs boson
/ Janot, Patrick (CERN) ; Kado, M
For twelve years, LEP revolutionized the knowledge of electroweak symmetry breaking within the standard model, and the direct discovery of the Higgs boson would have been the crowning achievement. Searches at the Z resonance and above the W/sup +/W/sup -/ threshold allowed an unambiguous lower limit on the mass of the standard model Higgs boson to set be at 114.1 GeV.c/sup -2/. [...]
