Higgs Production via Gluon-Induced Weak Boson Fusion
One of the primary goals of the CERN Large Hadron Collider (LHC) that will go into full operation soon is to illuminate the electro-weak symmetry breaking mechanism. The favoured mechanism — the Higgs mechanism — predicts the existence of a Higgs boson. The Higgs boson will be produced at the LHC mainly through gluon fusion which has the largest cross section there. While for Higgs masses of mH...
متن کاملHiggs Boson and Z Boson
The recent discovery of a Higgs boson at the LHC is a milestone in the quest to understand electroweak symmetry breaking. It is an important particle because it is responsible for the Higgs mechanism by which all particles acquire mass. The existence of a particle with zero spin suggests the need for new physics beyond the standard model. Z bosons are known to naturally exist in well-motivate...
متن کاملNext-to-leading order jet distributions for Higgs boson production via weak-boson fusion
The weak-boson fusion process is expected to provide crucial information on Higgs boson couplings at the Large Hadron Collider at CERN. The achievable statistical accuracy demands comparison with next-to-leading order QCD calculations, which are presented here in the form of a fully flexible parton Monte Carlo program. QCD corrections are determined for jet distributions and are shown to be mod...
متن کاملWeak boson scattering in Gauge-Higgs Unification
The scattering amplitude for the longitudinal weak bosons is investigated in the SU(3) gauge-Higgs unification as a function of the scattering energy, the Wilson line phase θH and the warp factor. The θH-dependence of the amplitude is quite different in the flat and the warped spacetimes. Generically the amplitude is enhanced for θH = O(1) in the warped case while it is almost independent of θH...
متن کاملAnomalous Higgs Boson Production and Decay
A non-standard symmetry breaking sector may lead to derivative couplings of the Higgs boson and thereby to anomalous interactions with the electroweak gauge bosons. In the framework of gauge-invariant effective Lagrangians the resulting changes in Higgs boson production and decay mechanisms are related to anomalous triple vector boson couplings. Using low energy constraints on the dimension-six...
