Measurement of the charged particle multiplicity distribution in hadronic Z decays

D. Decamp, +399 more
- 12 Dec 1991 - 
TL;DR: In this article, the authors measured the charged particle multiplicity distribution of hadronic Z decays using the ALEPH detector at LEP and found that the distribution has a mean 〈n〉=20.85± 0.24 and a dispersion D=6.34±0.12.
Journal ArticleDOI

Improved measurements of electroweak parameters from $Z$ decays into fermion pairs

D. Decamp, +400 more
TL;DR: In this paper, the properties of the Z resonance were measured on the basis of 190 000Z decays into fermion pairs collected with the ALEPH detector at LEP, and the forward-backward asymmetry in leptonic decays was used to determine the ratio of vector to axial-vector coupling constants of leptons.
Journal ArticleDOI

Measurement of the strong coupling constant αs from global event-shape variables of hadronic Z decays

D. Decampo, +387 more
- 21 Feb 1991 - 
TL;DR: In this article, an analysis of global event-shape variables has been carried out for the reaction e+e−→Z0→hadrons to measure the strong coupling constant αs.
Journal ArticleDOI

Properties of hadronic Z decays and test of QCD generators

D. Buskulic, +404 more
TL;DR: In this paper, the authors presented distributions of event shape variables, jet roduction rates and charged particle momenta obtained from 53 000 hadronicZ decays, compared to the predictions of the QCD+hadronization models JETSET, ARIADNE and HERWIG, and used to optimize several model parameters.
