Production rate of bb(bar) quark pairs from gluons and bb(bar)bb(bar) events in hadronic Z Decays
The OPAL collaboration, G. Abbiendi
The rates are measured per hadronic Z decay for gluon splitting to bb(bar) quark pairs, g_bb, and of events containing two bb(bar) quark pairs, g_4b, using a sample of four-jet eve…
A Measurement of the Rate of Charm Production in W Decays
The OPAL collaboration, G. Abbiendi
Using data recorded at centre-of-mass energies around 183 GeV and 189 GeV with the OPAL detector at LEP, the fundamental coupling of the charm quark to the W boson has been studied…
Measurement of the Mass and Width of the W Boson in e+e- Collisions at 189 GeV
The OPAL collaboration, G. Abbiendi
The mass and width of the W boson are determined in e+e- collisions at LEP using 183 pb^-1 of data recorded at a centre-of-mass energy roots=189 GeV with the OPAL detector. The inv…
Searches for prompt light gravitino signatures in e+e- Collisions at sqrt{s}=189GeV
The OPAL collaboration, G. Abbiendi
Searches for final states expected in models with light gravitinos have been performed, including experimental topologies with multi-leptons with missing energy, leptons and photon…
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…
Photonic events with missing energy in e+e- collisions at sqrt(s)=189 GeV
G. Abbiendi, the OPAL collaboration
Photonic events with large missing energy have been observed in e+e- collisions at a centre-of-mass energy of 189GeV using the OPAL detector at LEP. Results are presented for event…
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…
