Measurement of the e+e- -> W+W- cross section and W decay branching fractions at LEP
The OPAL collaboration
From a total data sample of 701.1 pb^-1 recorded with e+e- centre-of-mass energies of sqrt = 161-209 GeV with the OPAL detector at LEP, 11693 W-pair candidate events are selected.…
Bose-Einstein study of position-momentum correlations of charged pions in hadronic Z0 decays
The OPAL collaboration
A study of Bose-Einstein correlations in pairs of identically charged pions produced in e+e- annihilations at the Z0 peak has been performed for the first time assuming a non-stati…
Inclusive Production of Charged Hadrons in Photon-Photon Collisions
The OPAL collaboration
The inclusive production of charged hadrons in the collisions of quasi-real photons e+e- -> e+e- +X has been measured using the OPAL detector at LEP. The data were taken at e+e- ce…
Radiation damage to neutron and proton irradiated GaAs particle detectors
M. Rogalla, Th. Eich, N. Evans +8
The radiation damage in 200 um thick Schottky diodes made on semi-insulating (SI) undoped GaAs Liquid Encapsulated Czochralski (LEC) bulk material with resistivities between 0.4 an…
