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

Measurement of the strong coupling constant αs and the vector and axial-vector spectral functions in hadronic tau decays the opal collaboration

K. Ackerstaff, +337 more
TL;DR: In this paper, the spectral functions of the vector current and the axial-vector current have been measured in hadronic decay using the OPAL detector at LEP and a simultaneous determination of the strong coupling constant was performed within the framework of the operator product expansion.
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.
Journal ArticleDOI

QCD studies with e(+)e(-) annihilation data at 172-189 GeV

Giovanni Abbiendi, +335 more
TL;DR: In this paper, the authors have studied hadronic events from the center-of-mass energies at center of mass energies of 172, 183, and 189 GeV at the OPAL detector, and extracted measurements of the strong coupling, the mean charged particle multiplicity, and the peak position.
