Flavour Independent hA Search and Two Higgs Doublet Model Interpretation of Neutral Higgs Boson Searches at LEP

The OPAL collaboration, G. Abbiendi

Upper limits on the cross-section of the pair-production process e+e- -> h0A0 assuming 100% decays into hadrons, are derived from a new search for the h0A0 -> hadrons topology, ind…

Measurement of the Strange Spectral Function in Hadronic tau Decays

The OPAL collaboration, G. Abbiendi

Tau lepton decays with open strangeness in the final state are measured with the OPAL detector at LEP to determine the strange hadronic spectral function of the tau lepton. The dec…

Measurement of charged current triple gauge boson couplings using W pairs at LEP

The OPAL collaboration, G. Abbiendi

Triple gauge boson couplings are measured from W-pair and single photon events recorded by the OPAL detector at LEP at center-of-mass energies between 183 - 209 GeV with a total in…

Tests of model of color reconnection and a search for glueballs using gluon jets with a rapidity gap

The OPAL collaboration, G. Abbiendi

Gluon jets with a mean energy of 22 GeV and purity of 95% are selected from hadronic Z0 decay events produced in e+e- annihilations. A subsample of these jets is identified which e…

Measurement of Isolated Prompt Photon Production in Photon-Photon Collisions at sqrt(s)_ee=183-209 GeV

The OPAL collaboration, G. Abbiendi

For the first time at LEP the production of prompt photons is studied in the collisions of quasi-real photons using the OPAL data taken at e+e- centre-of-mass energies between 183…

Search for pair-produced leptoquarks in e+e- interactions at sqrt(s) = 189 - 209 GeV

The OPAL collaboration, G. Abbiendi

A search for pair-produced leptoquarks is performed using e+e- collision events collected by the OPAL detector at LEP at centre-of-mass energies between 189 and 209 GeV. The data s…
