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…
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…
