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…
Bose-Einstein Correlations in e+e- to W+W- at 172 and 183 GeV
The OPAL Collaboration, G. Abbiendi et al
Bose-Einstein correlations between like-charge pions are studied in hadronic final states produced by e+e- annihilations at center-of-mass energies of 172 and 183 GeV. Three event…
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 Scalar Top and Scalar Bottom Quarks at sqrt(s) = 183 GeV at LEP
The OPAL Collaboration, K. Ackerstaff et al
Searches for a scalar top quark and a scalar bottom quark have been performed using a total data sample of 56.8 pb-1 at a centre-of-mass energy of 183 GeV collected with the OPAL d…
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…
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…
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…
Production of f_0(980), f_2(1270) and ϕ(1020) in hadronic Z^0 decay
The OPAL Collaboration, K. Ackerstaff et al
Inclusive production of the f_0(980), f_2(1270) and ϕ(1020) resonances has been studied in a sample of 4.3 million hadronic Z^0 decays from the OPAL experiment at LEP. A coupled ch…
