Measurement of the strong coupling alpha_S from the three-jet rate in e+e- - annihilation using JADE data

Jochen Schieck, Siegfried Bethke, Stefan Kluth +3

We present a measurement of the strong coupling alpha_S using the three-jet rate measured with the Durham algorithm in e+e- -annihilation using data of the JADE experiment at centr…

Determination of αS using OPAL hadronic event shapes at sqrt(s) = 91 - 209 GeV and resummed NNLO calculations

The OPAL Collaboration

Hadronic event shape distributions from e+e- annihilation measured by the OPAL experiment at centre-of-mass energies between 91 GeV and 209 GeV are used to determine the strong cou…

Sigma-antihyperon correlations in Z0 decay and investigation of the baryon production mechanism

The OPAL Collaboration

Data collected around sqrt{s}=91 GeV by the OPAL experiment at the LEP e+e- collider are used to study the mechanism of baryon formation. As the signature, the fraction of Sigma-hy…

Tests of analytical hadronisation models using event shape moments in {\epem} annihilation

C. Pahl, S. Bethke, O. Biebel +2

Predictions of analytical models for hadronisation, namely the dispersive model, the shape function and the single dressed gluon approximation, are compared with moments of hadroni…

Study of moments of event shapes and a determination of \as using \epem annihilation data from \Jade

Christoph Pahl, Siegfried Bethke, Stefan Kluth +1

Data from \epem annihilation into hadrons, collected by the \Jade experiment at centre-of-mass energies between 14 GeV and 44 GeV, are used to study moments of event shape distribu…
