W Physics at LEP
A summary of the W-boson properties measured by the four LEP collaborations is presented here. These properties are updated to take into account the most recent results presented at the ICHEP98 Conference. 1 WW cross sections and W branching fractions After the period of running at the Z, the centre-of-mass energy of LEP has been progressively increased from 161 GeV, i.e., just above the W pair...
متن کاملW and Z Physics
The electroweak theory elegantly combines the electromagnetic and weak forces, explaining a wide range of interactions using a gauge theory with just three parameters. The theory predicted the W and Z weak gauge bosons before they were directly observed in 1983, and its detailed predictions of W and Z boson properties have been tested to such precision that they now serve as probes for new part...
متن کاملW physics at LEP
Studying the properties of the W boson plays a key role in precision tests of the Standard Model. The key measurements performed over the last decade will be reviewed. W-pair and single-W cross-sections and W decay branching fractions are determined and agree well with theoretical predictions. Including the analysis of differential distributions, trilinear and quartic couplings of the W boson t...
متن کاملExploring the Patterns of Evaluative Language in Physics Blurbs: The Appraisal Strategies in Focus
The current study qualitatively examined blurbs in the discipline of physics which is perceived to be less infused with evaluative resources and more objective and impersonal in its textual argumentation. The study followed the appraisal framework proposed by Martin and White (2005) to see how interpersonal meaning is textually constructed in blurbs. Findings indicated that writers of the blurb...
متن کاملTheoretical Aspects of W Physics
High-precision predictions for W-production processes are complicated by the instability of the W bosons, requirements of gauge in-variance, and the necessity to include radiative corrections. Salient features and recent progress concerning these issues are discussed for the process ee → WW → 4f. Abstract. High-precision predictions for W-production processes are complicated by the instability ...
