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.

Operation, optimisation, and performance of the DELPHI RICH detectors / Albrecht, E ; Apeldoorn, G V ; Augustinus, A ; Baillon, Paul ; Battaglia, Marco ; Bloch, D ; Boudinov, E ; Brunet, J M ; Carrié, P ; Cavalli, P et al.
The Ring Imaging Cherenkov detectors of DELPHI represent a large-scale particle identification system which covers almost the full angular acceptance of DELPHI. The combination of liquid and gas radiators (C sub 4 F sub 1 sub 0 , C sub 5 F sub 1 sub 2 , and C sub 6 F sub 1 sub 4) provides particle identification over the whole secondary particle momentum spectrum at LEP I and LEP II.

Precision measurements of gas refractivity by means of a Fabry-Perot interferometer illustrated by the monitoring of radiator refractivity in the DELPHI RICH detectors / Filippas-Tassos, A ; Davenport, M ; Fokitis, E ; Maltezos, S ; Patrinos, K
With an updated, flexible, highly efficient and easily installed system we obtained accurate refractivity (n-1) values. This system is a refractometer based on a Fabry-Perot interferometer and was used to monitor the refractivity of DELPHI RICH Cherenkov radiators near the VUV region. [...]

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. [...]

Selection of hadronic W-decays in DELPHI with feed forward neural networks - An update / Becks, K H ; Drees, J ; Müller, U ; Wahlen, H
Since 1998 feed forward neural networks have been successfully applied to select candidates of hadronic W-decays measured at different center of mass-energies by the DELPHI collaboration at the Large Electron Positron collider at CERN. To prepare the final publication, the neural network was adapted to all center of mass- energies. [...]

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.
