Radiative corrections to Higgs couplings with weak gauge bosons in custodial multi-Higgs models [PDF]

open access: yes, 2017
We calculate 1-loop radiative corrections to the hZZ and hWW couplings in models with next-to-simplest Higgs sectors satisfying the electroweak ρ parameter equal to 1 at tree level: the real Higgs singlet model, the two-Higgs doublet models, and the ...

Frustrated symmetries in multi-Higgs-doublet models [PDF]

open access: yesPhysics Letters B, 2010
Within multi-Higgs-doublet models, one can impose symmetries on the Higgs potential, either discrete or continuous, that mix several doublets. In two-Higgs-doublet model any such symmetry can be conserved or spontaneously violated after the electroweak ...

Classifying accidental symmetries in multi-Higgs doublet models [PDF]

open access: yesPhysical Review D, 2019
The potential of $n$-Higgs Doublet Models ($n$HDMs) contains a large number of SU(2)$_L$-preserving accidental symmetries as subgroups of the symplectic group Sp(2$n)$.

Family Symmetries and Multi Higgs Doublet Models [PDF]

open access: yesSymmetry, 2020
Imposing a family symmetry on the Standard Model in order to reduce the number of its free parameters, due to the Schur’s Lemma, requires an explicit breaking of this symmetry.

FCNCs in supersymmetric multi-Higgs doublet models [PDF]

open access: yes, 2005
We conduct a general discussion of supersymmetric models with three families in the Higgs sector. We analyse the scalar potential, and investigate the minima conditions, deriving the mass matrices for the scalar, pseudoscalar and charged states ...

Leptogenesis in models with multi-Higgs bosons [PDF]

open access: yesModern Physics Letters A, 2002
We study the leptogenesis scenario in models with multi-Higgs doublets. It is pointed out that the washing-out process through the effective dimension five interactions, which has not been taken into account seriously in the conventional scenario, can be

Mapping Charge Interactions in Intrinsically Disordered Proteins. [PDF]

open access: yesAdv Sci (Weinh)
This study presents analytical models to predict intrachain distances in intrinsically disordered proteins (IDPs), accounting for charge patterning, salt concentration, and electrostatic effects. Validated against single‐molecule FRET data, a minimal‐parameter polymer model is identified that captures key interactions and chain dimensions. These models

Symmetry and decoupling in multi-Higgs boson models

open access: yesPhysical Review D, 2021
We study the scalar sector of the most general multi-Higgs doublet model satisfying explicitly an exact symmetry. We prove that such a model will exhibit decoupling if and only if the vacuum also satisfies the same symmetry. This general property is also

Group-theoretic restrictions on generation of CP-violation in multi-Higgs-doublet models [PDF]

open access: yes, 2015
A bstractIt has been known since decades that imposing a symmetry group G on the scalar sector of multi-Higgs-doublet models has consequences for CP -violation. In all examples of two- and three-Higgs-doublet models equipped with symmetries, one observes

Minima of multi-Higgs potentials with triplets of Δ(3n2) and Δ(6n2)

open access: yesPhysics Letters B, 2017
We analyse the minima of scalar potentials for multi-Higgs models where the scalars are arranged as either one triplet or two triplets of the discrete symmetries A4, S4, Δ(27), Δ(54), as well as Δ(3n2) and Δ(6n2) with n>3.
