Searches for Gauge-Mediated Supersymmetry Breaking Topologies in e+e- collisions at LEP2
The OPAL Collaboration, G. Abbiendi
Searches were performed for topologies predicted by gauge-mediated Supersymmetry breaking models (GMSB). All possible lifetimes of the next-to-lightest SUSY particle (NLSP), either…
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…
Search for Anomalous Production of Di-lepton Events with Missing Transverse Momentum in e+e- Collisions at sqrt(s) = 183-209 GeV
The OPAL collaboration, G. Abbiendi
In total 1317 di-lepton events with significant missing transverse momentum were identified in a total data sample of 680 pb-1 collected at e+e- centre-of-mass energies ranging fro…
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…
