A bstractWe explore the phenomenology of a unique three-Higgs-doublet model based on the single CP symmetry of order 4 (CP4) without any accidental symmetries. The CP4 symmetry is imposed on the scalar potential and Yukawa interactions, strongly shaping both sectors of the model and leading to a very characteristic phenomenology. The scalar sector is analyzed in detail, and in the Yukawa sector we list all possible CP4-symmetric structures which do not run into immediate conflict with… 

Constraining CP4 3HDM with Top Quark Decays

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

Radiative neutrino masses from order-4 CP symmetry

A bstractGeneralized CP symmetry of order 4 (CP4) is surprisingly powerful in shaping scalar and quark sectors of multi-Higgs models. Here, we extend this framework to the neutrino sector. We build

Dark matter from CP symmetry of order 4: evolution in the asymmetric regime

Multi-Higgs models equipped with global symmetries produce scalar dark matter (DM) candidates stabilized by the unbroken symmetry. It is remarkable that a conserved CP symmetry can also stabilize DM

Radiative neutrino masses from order-4 CP symmetry

Generalized CP symmetry of order 4 (CP4) is surprisingly powerful in shaping scalar and quark sectors of multi-Higgs models. Here, we extend this framework to the neutrino sector. We build two simple

Symmetries and mass degeneracies in the scalar sector

A bstractWe explore some aspects of models with two and three SU(2) scalar doublets that lead to mass degeneracies among some of the physical scalars. In Higgs sectors with two scalar doublets, the

Anomaly-free axion dark matter in three Higgs doublet model and its phenomenological implications

We study phenomenological implications of an axion that arises as a pseudo Nambu-Goldstone boson due to the spontaneous breaking of anomaly-free global flavor symmetry. One interesting possibility

Predictive extended 3HDM with $S_4$ family symmetry

We propose extended 3HDM and 4HDM theories where the SM gauge symmetry is enlarged by the inclusion of the spontaneously broken S 4 discrete symmetry group, supplemented by the preserved Z 2 and

Fermion masses and mixings and g − 2 muon anomaly in a 3-3-1 model with D 4 family symmetry

We propose a predictive model based on the SU ( 3 ) C × SU ( 3 ) L × U ( 1 ) X gauge symmetry, which is supplemented by the D 4 family symmetry and several auxiliary cyclic symmetries whose

Extending trinity to the scalar sector through discrete flavoured symmetries

We conjecture the existence of a relation between elementary scalars and fermions, making it plausible the existence of three Higgs doublets. We introduce a Trinity Principle (TP) which, given the

Investigation of the GCP Structure of Three-Higgs-Doublet Models and a General Method to Derive Boundedness Constraints for Multi-Higgs Potentials

In this thesis the theoretical analysis of an inert three-Higgs-doublet model with a generalized CP symmetry is presented. The phenomenological consequences of astrophysical observables and

A new type of CP symmetry, family replication and fermion mass hierarchies

We study a two-Higgs doublet model with four generalised CP symmetries in the scalar sector. Electroweak symmetry breaking leads automatically to spontaneous breaking of two of them. We require that

Maximally symmetric two Higgs doublet model with natural standard model alignment

A bstractWe study the Higgs mass spectrum as predicted by a Maximally Symmetric Two Higgs Doublet Model (MS-2HDM) potential based on the SO(5) group, softly broken by bilinear Higgs mass terms. We

CP-violating phenomenology of flavor conserving two Higgs doublet models

We analyze the constraints on CP-violating, flavor conserving two Higgs doublet models implied by measurements of Higgs boson properties at the Large Hadron Collider (LHC) and by the nonobservation

Constraining multi-Higgs flavour models

To study a flavour model with a non-minimal Higgs sector one must first define the symmetries of the fields; then identify what types of vacua exist and how they may break the symmetries; and finally

CP-conserving multi-Higgs model with irremovable complex coefficients

Models beyond the Standard Model (bSM) often involve elaborate Higgs sectors, which can be a source of CP-violation. It brings up the question of recognizing in an efficient way whether a model is

Conditions for CP-violation in the general two-Higgs-doublet model

The most general Higgs potential of the two-Higgs-doublet model (2HDM) contains three squared-mass parameters and seven quartic self-coupling parameters. Among these, one squared-mass parameter and

In the alignment limit of a multi-doublet Higgs sector, one of the Higgs mass eigenstates aligns in field space with the direction of the scalar field vacuum expectation values, and its couplings
