Investigation of induced radioactivity in the CERN Large Electron Positron collider for its decommissioning / Silari, Marco ; Ulrici, Luisa
The future installation of the Large Hadron Collider in the tunnel formerly housing the Large Electron Positron collider (LEP) required the dismantling of the latter after 11-year operation. As required by the French legislation, an extensive theoretical study was conducted before decommissioning to establish the possible activation paths both in the accelerator and in the four experiments (L3, ALEPH, OPAL and DELPHI) installed around the ring.

Review of the Properties of the W Boson at LEP, and the Precision Determination of its Mass / Ströhmer, R (Munich U.)
We review the precision measurement of the mass and couplings of the W Boson at LEP. The total and differential W+W- cross section is used to extract the WWZ and WWgamma couplings. [...]

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/. [...]

The number of neutrinos and the Z line shape / Blondel, A (Faculte des Sci)
Thanks to a precise calibration and monitoring of the LEP beam energy the Z resonance line shape has been precisely measured, hence permitting accurate determinations of the Z mass and width. A large effort was spent on experiments for the measurement of the LEP luminosity, enabling the number of neutrino types to be precisely determined. [...]
