Colour reconnection studies in e+e- -> W+W- at sqrt(s)=183 GeV

The OPAL Collaboration, G. Abbiendi et al

The predicted effects of final state interactions such as colour reconnection are investigated by measuring properties of hadronic decays of W bosons, recorded at a centre-of-mass…

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…

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…

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…

Measurements of the B^0_s and Λ_b Lifetimes

The OPAL Collaboration, K. Ackerstaff et al

This paper presents updated measurements of the lifetimes of the B^0_s meson and the Λ_b baryon using 4.4 million hadronic Z^0 decays recorded by the OPAL detector at LEP from 1990…

Measurement of the Photon Structure Function F_2^gamma at Low x

The OPAL Collaboration, K. Ackerstaff et al

Deep inelastic electron-photon scattering is studied using e+e- data collected by the OPAL detector at centre-of-mass energies sqrt{s_ee} ~ M_{Z^0}. The photon structure function F…
