W 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...

Quartic gauge couplings from e + e − → W + W − Z

Effective quartic gauge couplings on tree level appear in a strong interacting Higgs scenario, which could be relevant, e.g. if no standard model Higgs would be found 1. This scenario can be described in terms of an effective chiral Lagrangian valid for invariant energies m W,Z < √ s < 4πv, where the vacuum expectation value due to electroweak symmetry breaking is v = (√ 2G F) −1 ≃ 246 GeV. It ...

Extending W for Object-Z

This paper presents a logic for Object-Z which extends W, the logic for Z adopted as the basis of the deductive system in the Z Base Standard. The logic provides a basis on which tool support for reasoning about Object-Z speciications can be developed. It also formalises the intended meaning of Object-Z constructs and hence provides an abstract, axiomatic semantics of the language.

Hadronic ZZ, W-W+, and W+/-Z production with QCD corrections and leptonic decays.

The processes p p (−) → V1V2 +X → l1l̄1l2l̄2 +X, where Vi = W or Z and li denotes a lepton, are calculated to O(αs). Total and differential cross sections, with acceptance cuts imposed on the final state leptons, are given for the Tevatron and LHC center of mass energies. Inclusive and exclusive 0-jet and 1jet cross sections are given. The transverse momenta spectra of the leptons are significant...
