Journal ArticleDOI

Electroweak measurements in electron positron collisions at W-boson-pair energies at LEP

S. Schael, +1675 more
- 30 Nov 2013 - 
TL;DR: In this paper, the results of the four LEP experiments were combined to determine fundamental properties of the W boson and the electroweak theory, including the branching fraction of W and the trilinear gauge-boson self-couplings.
Journal ArticleDOI

Search for neutral MSSM Higgs bosons at LEP

S. Schael, +1282 more
TL;DR: In this paper, four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the minimal supersymmetric standard model (MSSM).
Journal ArticleDOI

Decay-mode independent searches for new scalar bosons with the OPAL detector at LEP

Giovanni Abbiendi, +295 more
TL;DR: In this paper, the authors describe topological searches for neutral scalar bosons S0 produced in association with a Z0 boson via the Bjorken process at centre-of-mass energies of 91 GeV and 183-209 GeV.
Journal ArticleDOI

Photonic events with missing energy in e+e- collisions at √s = 189 GeV

Giovanni Abbiendi, +324 more
TL;DR: In this article, the authors derived upper bounds on the number of light neutrino species in the presence of a single photon or with an acoplanar photon pair in the OPAL detector at LEP.
Journal ArticleDOI

QCD analyses and determinations of αs in e+e− annihilation at energies between 35 and 189 GeV

P. Pfeifenschneider, +336 more
TL;DR: In this article, the authors employ data taken by the JADE and OPAL experiments for an integrated QCD study in hadronic e¯¯ $+$€+$¯¯¯¯ e $€-$¯¯¯¯ annihilations at c.m.s. energies ranging from 35 GeV through 189 GeV.
