First observation of two hyperfine transitions in antiprotonic He-3
S. Friedreich, D. Barna, F. Caspers +11
We report on the first experimental results for microwave spectroscopy of the hyperfine structure of antiprotonic He-3. Due to the helium nuclear spin, antiprotonic He-3 has a more…
Collision Induced Relaxations within the Antiprotonic Helium Hyperfine Structure
T. Pask, D. Barna, A. Dax +10
We report the first measurements of the inelastic spin exchange collision rate between the Hyperfine (HF) levels of antiprotonic helium. We measure the time dependent evolution of…
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…
Search for Invisibly Decaying Higgs Bosons with Large Decay Width Using the OPAL Detector at LEP
The OPAL collaboration
This paper describes a topological search for an invisibly decaying Higgs boson,H, produced via the Bjorken process (e+e- -> HZ). The analysis is based on data recorded using the O…
