Higgs Coupling Measurements and the Scale of New Physics

Web19 de jul. de 2016 · For the measured Higgs boson mass of GeV the limit of heavy top quarks provides a reliable approximation as long as the relative QCD corrections are scaled with the full mass-dependent LO cross section. In this limit the Higgs coupling to gluons can be described by an effective Lagrangian. The Higgs mechanism was incorporated into modern particle physics by Steven Weinberg and Abdus Salam, and is an essential part of the Standard Model. In the Standard Model, at temperatures high enough that electroweak symmetry is unbroken, all elementary particles are massless. At a critical … Ver mais In the Standard Model of particle physics, the Higgs mechanism is essential to explain the generation mechanism of the property "mass" for gauge bosons.

WebThus the Higgs mechanism is not related to a new fundamental force. At the quantum level it is the coupling constants that define the type of interaction and are fundamental. The Higgs boson is in the electroweak sector and, as a neutral elementary particle, interacts only with the weak coupling constant at the vertices. Share Cite WebA. Triple Higgs Boson Self-Coupling Via γγ → ffHH¯ (f = b,t) To illustrate our results of the sensitivity to the HHH triple Higgs boson self-coupling, we show the dependence of the cross-section on the center-of-mass energy of √ s = 500−3000 GeV for γγ → t¯tHH in Fig. 2 for several values of the Higgs boson mass M H = 120,140 GeV.

WebFinally we show that introducing a moderately large nonminimal coupling for the Higgs field the bound can shift to larger values and be reconciled with the LHC measurements of the Higgs mass.
