A measurement of the tau mass and the first CPT test with tau leptons

G. Abbiendi, the OPAL collaboration

We measure the mass of the tau lepton to be 1775.1+-1.6(stat)+-1.0(syst.) MeV using tau pairs from Z0 decays. To test CPT invariance we compare the masses of the positively and neg…

Z boson pair production in e+e- collisions at sqrt(s) = 183 and 189 GeV

The OPAL collaboration, G. Abbiendi

A study of Z boson pair production in e+e- annihilation at center-of-mass energies near 183 GeV and 189 GeV is reported. Final states containing only leptons, (l+l-l+l- and l+l-nu…

Search for new Physics in rare B Decays

The OPAL collaboration, G. Abbiendi

A search for the decay B+- to K+-K+-pi-+ was performed using data collected by the OPAL detector at LEP. These decays are strongly suppressed in the Standard Model but could occur…

Measurement of the W+W-gamma Cross-section and First direct Limits on Anomalous Electroweak Quartic Gauge Couplings

The OPAL collaboration, G. Abbiendi

A study of W+W- events accompanied by hard photon radiation produced in e+e- collisions at LEP is presented. Events consistent with two on-shell W-bosons and an isolated photon are…

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…

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…

Spin alignment of leading K*(892)^0 mesons in hadronic Z^0 decays

The OPAL Collaboration, K. Ackerstaff et al

Helicity density matrix elements for inclusive K*(892)^0 mesons from hadronic Z^0 decays have been measured over the full range of K^*0 momentum using data taken with the OPAL expe…
