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…

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…

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…

Search for Higgs Bosons and New Particles Decaying into Two Photons at sqrt(s) = 183 GeV

The OPAL Collaboration, K. Ackerstaff et al

A search for the resonant production of high mass photon pairs associated with a leptonic or hadronic system has been performed using a data sample of 57.7 pb-1 collected at an ave…

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…

Search for Stable and Long-Lived Massive Charged Particles with the OPAL Detector at LEP in e+e- Collisions at \sqrt{s}=130-183 GeV

The OPAL Collaboration, K. Ackerstaff et al

A search for stable and long-lived massive particles of electric charge |Q/e| = 1 or 2/3, pair-produced in e+e- collisions at centre-of-mass energies from 130 to 183 GeV, is report…
