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…

Search for Neutral Higgs Bosons in e+e- Collisions at sqrt(s) ~189GeV

The OPAL collaboration, G. Abbiendo

A search for neutral Higgs bosons has been performed with the OPAL detector at LEP, using approximately 170 pb-1 of e+e- collision data collected at sqrt(s)~189GeV. Searches have b…

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…

Search for Baryon and Lepton Number Violating Z0 Decays

The OPAL Collaboration, G. Abbiendi et al

Using data collected with the OPAL detector at LEP, we have searched for the processes e+e- -> Z0 -> p e-, p mu- and the charge conjugate final-states. These would violate the cons…
