Higgs self coupling

WebThe existence of a second Higgs doublet in Nature could lead to a cosmological first order electroweak phase transition and explain the origin of the matter-antimatter asymmetry in the Universe. We explore the parameter space of such a two-Higgs-doublet-model and s Web1 de abr. de 2015 · We find, moreover, that the Higgs self-coupling constant λcan be related to the gauge coupling constants as λ=gY22ξ′2+gsu222ξ2where ξ′2and ξ2are two numbers whose physical interpretation and their classical estimation at electroweak and Planck scales will be discussed in Sections 5and 6of this paper.

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.
