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…
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…
Measurement of the Average Polarization of b Baryons in Hadronic Z^0 Decays
The OPAL Collaboration, G. Abbiendi et al
In the Standard Model, b quarks produced in e^+e^- annihilation at the Z^0 peak have a large average longitudinal polarization of -0.94. Some fraction of this polarization is expec…
An upper limit on the anomalous magnetic moment of the τlepton
The OPAL Collaboration, K. Ackerstaff et al
Using radiative Z^0 -> τ^+ τ^- γevents collected with the OPAL detector at LEP at \sqrt{s}= M_Z during 1990-95, a direct study of the electromagnetic current at the τγvertex has be…
Search for an Excess in the Production of Four-Jet Events from e^+e^- Collisions at \sqrt{s} = 130-184 GeV
The OPAL Collaboration, K. Ackerstaff et al
Events with four distinct jets from e^+e^- collisions, collected by the OPAL detector at centre-of-mass energies between 130 and 184 GeV, are analysed for a peak in the sum of dije…
