Constraining CP4 3HDM with Top Quark Decays
Universe, 2021 CP4 3HDM is a unique three-Higgs-doublet model equipped with a higher-order CP-symmetry in the scalar and Yukawa sector. Based on a single assumption (the minimal model with a CP-symmetry of order 4 and no accidental symmetry), it leads to a remarkable ...

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.

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 ...

Nonstandard Yukawa Couplings and Higgs Portal Dark Matter [PDF]
, 2015 We study the implications of non-standard Higgs Yukawa couplings to light quarks on Higgs-portal dark matter phenomenology. Saturating the present experimental bounds on up-quark, down-quark, or strange-quark Yukawa couplings, the predicted direct dark ...

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 ...

CP violation in a model with Higgs triplets
Journal of High Energy Physics, 2023 We discuss CP-violation in a model with a real and a complex isospin triplet Higgs fields without introducing any symmetries except for the electroweak gauge symmetry.
