Measurement of the Strong Coupling alpha_S from the Four-Jet Rate in e+e- annihilation

Jochen Schieck

Data from e+e- annihilation into hadrons at centre-of-mass energies between 91 GeV and 209 GeV are used to study the four-jet rate as a function of the Durham algorithm's resolutio…

Mulit-Photon Events with Large Missing energy in e+e- collisions at sqrt(s)=192-209 GeV

The OPAL collaboration, G. Abbiendi

Events with a final state consisting of two or more photons and large missing transverse energy have been observed in e+e- collisions at centre-of-mass energies in the range 192 -…

First results from the CERN Axion Solar Telescope (CAST)

CAST Collaboration

Hypothetical axion-like particles with a two-photon interaction would be produced in the Sun by the Primakoff process. In a laboratory magnetic field (``axion helioscope'') they wo…

Search for Radions at LEP2

The OPAL collaboration, G. Abbiendi

A new scalar resonance, called the radion, with couplings to fermions and bosons similar to those of the Higgs boson, is predicted in the framework of Randall-Sundrum models, propo…

Measurement of Rb in e+e- Collisions at 182 - 209 GeV

The OPAL Collaboration, G. Abbiendi

Measurements of Rb, the ratio of the bbbar cross-section to the qqbar cross- section in e+e- collisions, are presented. The data were collected by the OPAL experiment at LEP at cen…
