A Measurement of the Product Branching Ratio f(b->Lambda_b).BR(Lambda_b->Lambda X) in Z0 Decays
The OPAL Collaboration, G. Abbiendi et al
The product branching ratio, f(b->Lambda_b).BR(Lambda_b->Lambda X), where Lambda_b denotes any weakly-decaying b-baryon, has been measured using the OPAL detector at LEP. Lambda_b…
A Measurement of the tau->electron Branching Ratio
The OPAL Collaboration, G. Abbiendi et al
The branching ratio for the decay tau->e nue nutau has been measured using Z0 decay data collected by the OPAL experiment at LEP. In total 33073 tau->e nue nutau candidates were id…
Bose-Einstein Correlations in e+e- to W+W- at 172 and 183 GeV
The OPAL Collaboration, G. Abbiendi et al
Bose-Einstein correlations between like-charge pions are studied in hadronic final states produced by e+e- annihilations at center-of-mass energies of 172 and 183 GeV. Three event…
Measurement of Three-jet Distributions in Photoproduction at HERA
ZEUS Collaboration
The cross section for the photoproduction of events containing three jets with a three-jet invariant mass of M_3J > 50 GeV has been measured with the ZEUS detector at HERA. The thr…
Search for Anomalous Photonic Events with Missing Energy in e+e- Collisions at Ecm = 130, 136 and 183 GeV
The OPAL Collaboration, G. Abbiendi et al
Photonic events with large missing energy have been observed in e+e- collisions at centre-of-mass energies of 130, 136 and 183 GeV collected in 1997 using the OPAL detector at LEP.…
Measurement of the Semileptonic Branching Ratio of Charm Hadrons Produced in Z to ccbar Decays
The OPAL Collaboration, G. Abbiendi et al
The inclusive charm hadron semileptonic branching fractions B(c to e) and B(c to mu) in Z to ccbar events have been determined using 4.4 million hadronic Z decays collected with th…
