Nullification of multi-Higgs threshold amplitudes in the standard model [PDF]
Physics Letters B, 1993 We show that nullification of all tree-order threshold amplitudes involving Higgs particles in the Standard Model occurs, provided that certain equations relating the masses of all existing elementary particles to the mass of the Higgs scalar are satisfied.

The mass-degenerate SM-like Higgs and anomaly of (g − 2) μ in μ-term extended NMSSM
Journal of High Energy Physics, 2022 We chose the μ-term extended next-to-minimal supersymmetric standard model (μNMSSM) for this work, and we perform a phenomenological study based on the assumption that the observed Standard Model (SM)-like Higgs is explained by the presence of a double ...

Pseudoscalar MSSM Higgs Production at NLO SUSY-QCD
Journal of High Energy Physics, 2023 One of the most important mechanisms at the Large Hadron Collider (LHC) for the production of the pseudoscalar Higgs boson of the Minimal Supersymmetric Standard Model (MSSM) is the loop-induced gluon fusion process gg → A.

CP violation in multi-Higgs supersymmetric models [PDF]
Nuclear Physics B, 1996 We consider supersymmetric extensions of the standard model with two pairs of Higgs doublets. We study the possibility of spontaneous $CP$ violation in these scenarios and present a model where the origin of $CP$ violation is soft, with all the complex phases in the Lagrangian derived from complex masses and vacuum expectation values (VEVs) of the ...

3HDM with ∆(27) symmetry and its phenomenological consequences
Journal of High Energy Physics, 2023 We perform a comprehensive analysis of a version of the 3-Higgs doublet model whose scalar potential is invariant under a global ∆(27) discrete symmetry and where the three scalar doublets are chosen to transform as a triplet under this discrete group ...

The invariant space of multi-Higgs doublet models [PDF]
Journal of High Energy Physics, 2021 Abstract In a model with more than one scalar doublet, the parameter space encloses both physical and unphysical information. Invariant theory provides a detailed description of the counting and characterization of the physical parameter space. The Hilbert series for the 3HDM is computed for the first time using partition analysis,

Benchmarking di-Higgs production in various extended Higgs sector models
Journal of High Energy Physics, 2022 We present a comprehensive study on Higgs pair production in various archetypical extended Higgs sectors such as the real and the complex 2-Higgs-Doublet Model, the 2-Higgs-Doublet Model augmented by a real singlet field and the Next-to-Minimal ...
