The invariant space of multi-Higgs doublet models [PDF]

open access: yesJournal 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,

3HDM with ∆(27) symmetry and its phenomenological consequences

open access: yesJournal 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 ...

Yukawa sector of multi-Higgs-doublet models in the presence of Abelian symmetries [PDF]

open access: yes, 2013
A general method for classifying the possible quark models of a multi-Higgs-doublet model, in the presence of Abelian symmetries, is presented.

A precision constraint on multi-Higgs-doublet models [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2008
We derive a general expression for Delta rho (or, equivalently, for the oblique parameter T) in the SU(2) x U(1) electroweak model with an arbitrary number of scalar SU(2) doublets, with hypercharge +-1/2, and an arbitrary number of scalar SU(2) singlets.

Multi-Higgs-Doublet Models

open access: yes, 1999
Abstract The scalar sector of the standard model (SM) consists of only one doublet with weak hypercharge Y = 1/2. Most extensions of the SM include an enlargement of the Higgs sector. There are many theoretical motivations to enlarge the scalar sector of the standard electroweak theory, even if one only considers extensions of that ...

New tools for dissecting the general 2HDM

open access: yesJournal of High Energy Physics, 2023
Two Higgs doublet models (2HDM) provide the low energy effective theory (EFT) description in many well motivated extensions of the Standard Model. It is therefore relevant to study their properties, as well as the theoretical constraints on these models.

Leading two-loop corrections to the Higgs boson masses in SUSY models with Dirac gauginos [PDF]

open access: yes, 2016

Collider phenomenology of new neutral scalars in a flavored multi-Higgs model

open access: yesPhysical Review D, 2023
In this work, we propose and explore for the first time a new collider signature of heavy neutral scalars typically found in many distinct classes of multi-Higgs models. This signature, particular relevant in the context of the Large Hadron Collider (LHC) measurements, is based on a topology with two charged leptons and four jets arising from first and

Benchmarking di-Higgs production in various extended Higgs sector models

open access: yesJournal 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 ...
