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

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

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

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

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

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

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

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

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

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

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

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

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

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
