### Title: Theory and phenomenology of two-Higgs-doublet models

- Physics
- 2012

We discuss theoretical and phenomenological aspects of two-Higgs-doublet extensions of the Standard Model. In general, these extensions have scalar mediated flavour changing neutral currents which…

### Symmetry constrained two Higgs doublet models

- PhysicsThe European Physical Journal C
- 2018

We study two-Higgs-doublet models (2HDM) where Abelian symmetries have been introduced, leading to a drastic reduction in the number of free parameters in the 2HDM. Our analysis is inspired in BGL…

### Higgs boson and vacuum stability in models with extended scalar sector

- Physics
- 2016

In this dissertation Two-Higgs-Doublet Models (2HDMs) with a Z2-symmetric scalar potential are studied from different perspectives. Two kinds of models, which differ by the choice of the vacuum…

### Flavor conservation in two-Higgs-doublet models

- PhysicsPhysical Review D
- 2018

In extensions of the Standard Model with two Higgs doublets, flavour changing Yukawa couplings of the neutral scalars may be present at tree level. In this work we consider the most general scenario…

### Various perspectives of Two Higgs Doublet models and Naturalness criteria

- Physics
- 2017

We study the implication of a criterion of naturalness for a broad class of two Higgs doublet models (2HDMs). In particular, we assume the cancellation of quadratic divergences in what are called the…

### Physical constraints on a class of two-Higgs doublet models with FCNC at tree level

- Physics
- 2014

A bstractWe analyse the constraints and some of the phenomenological implications of a class of two Higgs doublet models where there are flavour-changing neutral currents (FCNC) at tree level but the…

### Self-consistent Dark Matter simplified models with an s-channel scalar mediator

- Physics
- 2017

We examine Simplified Models in which fermionic DM interacts with Standard Model (SM) fermions via the exchange of an s-channel scalar mediator. The single-mediator version of this model is not gauge…

### Charged-Higgs phenomenology in the aligned two-Higgs-doublet model

- Physics
- 2010

The alignment in flavour space of the Yukawa matrices of a general two-Higgs-doublet model results in the absence of tree-level flavour-changing neutral currents. In addition to the usual fermion…

### Experimental signatures of fermiophobic Higgs bosons

- Physics
- 2000

Abstract. The most general Two Higgs Doublet Model potential without explicit CP violation depends on 10 real independent parameters. Excluding spontaneous CP violation results in two 7 parameter…

### Models of Yukawa interaction in the two Higgs doublet model, and their collider phenomenology

- Physics
- 2009

Possible models of Yukawa interaction are discussed in the two Higgs doublet model (THDM) under the discrete symmetry imposed to avoid the flavor changing neutral current at the leading order. It is…

### Experimental signature of a fermiophobic Higgs boson

- Physics
- 2000

The phenomenology of both Two Higgs Doublet Model models in the fermiophobic limit is investigated and the different branching ratios for the decays of the scalar particles are presented.

### Fermion number conservation and two-Higgs-doublet models without tree-level flavor-changing neutral currents

- Physics
- 2010

The charged fermion mass matrices are always invariant under U(1) 3 symmetry linked to the fermion number transformation. A class of two-Higgs-doublet models can be identified by requiring that the…

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

- Physics
- 2008

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…
