Corrections to oblique parameters induced by anomalous vector boson couplings
We study quadratically divergent radiative corrections to the oblique parameters at CERN LEP1 induced by non-standard vector boson self-couplings. We work in the Stückelberg formalism and regulate the divergences through a gauge-invariant higher derivative scheme. Using consistency arguments together with the data we find a limit on the anomalous magnetic moment ∆κ of the W-boson, |∆κ| ∼< 0.26.

متن کاملGenerating Vector Boson Masses
If the Higgs particle is never found, one will need an alternative theory for vector boson masses. I propose such a theory involving an antisymmetric tensor potential coupled to a gauge field.
متن کاملUsing Vector Boson Fusion
The sensitivity of the ATLAS experiment to low mass SM Higgs produced via Vector Boson Fusion mechanism with H → γγ is investigated. A cut based event selection has been chosen to optimize the expected signal significance with this decay mode. A signal significance of 2.2 σ may be achieved for MH = 130GeV with 30 fb of accumulated luminosity.
متن کاملTheoretical Uncertainties in the QCD
The differences are discussed between various next-to-leading order prescriptions for the QCD evolution of parton densities and structure functions. Their quantitative impact is understood to an accuracy of 0.02%. The uncertainties due to the freedom to choose the renormalization and factorization scales are studied. The quantitative consequences of the different uncertainties on the extraction...
