Higgs self coupling
Web1 de jul. de 2024 · The two main challenges of this measurement are the tiny cross section for Higgs-boson pair production (about 1000 times smaller than the production of a single Higgs boson) and the interference between processes that involve the self-coupling and those that do not. Web30 de jun. de 2024 · Many of the couplings of the Higgs boson could be measured to a precision of 1.5–4%, including the Higgs–top quark to a precision of 3% (currently known to 11%).

Suppose that the potential has its minimum, not at but at some non-zero value This can happen, for example, with a potential form such as .
Web13 de out. de 2024 · We study the measurement of Higgs boson self-couplings through 2 → 3 vector boson scattering (VBS) processes in the framework of Standard Model effective field theory (SMEFT) at both proton and lepton colliders. WebThe usual presentation of the super-Higgs mechanism introduces Goldstino and Gravitino self-couplings (or mass terms) by hand and shows that the resulting action is consistent under local supersymmetry [ 2 ]. One then applies a shift of the Gravitino to obtain a massive Gravitino action coupled to matter supercurrents.
WebThe self-coupling of the Higgs boson helps in reconstructing the scalar potential. The main objective of this paper is to extract Higgs self-coupling by numerically analyzing several scattering processes governed by two Higgs doublet models (2HDM). Web27 de dez. de 2024 · Using theoretical arguments supported by concrete models, we derive a bound on the ratio of self-coupling to single-Higgs coupling deviations in ultraviolet completions of the Standard Model where parameters are not fine-tuned. Broadly speaking, a one-loop hierarchy is allowed.
