Journal ArticleDOI

A Study of charged particle multiplicities in hadronic decays of the Z0

P. D. Acton, +315 more
TL;DR: In this paper, an analysis of multiplicity distributions of charged particles produced in Z ≥ hadronic decays is presented based on the analysis of 82941 events collected within 100 MeV of the Z ≥ 1.0 peak energy with the OPAL detector at LEP.
Journal ArticleDOI

A study of differences between quark and gluon jets using vertex tagging of quark jets

P. D. Acton, +326 more
TL;DR: In this paper, the authors used reconstructed secondary vertices from heavy quark decay in conjunction with energy ordering of the jets to anti-tag the gluon jets and found that the mean particle multiplicity is larger for gluons than for quark jets.
Journal ArticleDOI

A determination of αs( {Mathematical expression}) at LEP using resummed QCD calculations

P. D. Acton, +314 more
TL;DR: In this article, the strong coupling constant, αs, has been determined in hadronic decays of the Z0 resonance, using measurements of seven observables relating to global event shapes, energy correlations and jet rates.
Journal ArticleDOI

A study of Bose-Einstein correlations in e+e− annihilations at LEP

P. D. Acton, +312 more
- 05 Sep 1991 - 
TL;DR: In this paper, Bose-Einstein correlations between like-sign charged track pairs have been studied in e + e − annihilation hadronic events at centre-of-mass energies around the Z 0 peak as a function of Q, the four-momentum difference of the pair.
Journal ArticleDOI

A global determination of {Mathematical expression} at LEP

P. D. Acton, +310 more
TL;DR: In this paper, the value of the strong coupling constant was determined from a study of 15 different observables in hadronicZ¯¯¯¯0 and τ decays, including global event shape variables, jet production rates, energy correlations, the Z¯¯¯¯0 line shape and decay asymmetries and the hadronic branching fraction of τ-leptons.
