A Measurement of the tau->electron Branching Ratio

The OPAL Collaboration, G. Abbiendi et al

The branching ratio for the decay tau->e nue nutau has been measured using Z0 decay data collected by the OPAL experiment at LEP. In total 33073 tau->e nue nutau candidates were id…

Evaluation of the LEP Centre-of-Mass Energy Above the W-Pair Production Threshold

Michael D. Hildreth

Knowledge of the beam energy at LEP2 is of primary importance to set the absolute energy scale for the measurement of the W-boson mass. The beam energy above 80 GeV is derived from…

A Measurement of Rb using a Double Tagging Method

The OPAL Collaboration, G. Abbiendi et al

The fraction of Z to bbbar events in hadronic Z decays has been measured by the OPAL experiment using the data collected at LEP between 1992 and 1995. The Z to bbbar decays were ta…

Measurement of the Longitudinal Cross-Section using the Direction of the Thrust Axis in Hadronic Events at LEP

The OPAL Collaboration, G. Abbiendi et al

In the process e+e- to hadrons, one of the effects of gluon emission is to modify the 1+cos(theta)**2 form of the angular distribution of the thrust axis, an effect which may be qu…

A Study of Parton Fragmentation in Hadronic Z0 Decays Using Lambda-Lambdabar Correlations

The OPAL Collaboration, G. Abbiendi et al

The correlated production of Lambda and Lambdabar baryons has been studied using 4.3 million multihadronic Zo decays recorded with the OPAL detector at LEP. Di-lambda pairs were in…

First Measurement of Z/gamma* Production in Compton Scattering of Quasi-real Photons

OPAL Collaboration, G. Abbiendi et al

We report the first observation of Z/gamma* production in Compton scattering of quasi-real photons. This is a subprocess of the reaction e+e- to e+e-Z/gamma*, where one of the fina…
