Abstract:
We review the effects of new effective interactions on Higgs-boson phenomenology. New physics in the electroweak bosonic sector is expected to induce additional interactions between the Higgs doublet field and the electroweak gauge bosons, leading to anomalous Higgs couplings as well as anomalous gauge-boson self-interactions. Using a linearly realized SU (2)L× U (1)Y invariant effective Lagrangian to describe the bosonic sector of the Standard Model, we review the effects of the new effective interactions on the Higgs-boson production rates and decay modes. We summarize the results from searches for the new Higgs signatures induced by the anomalous interactions in order to constrain the scale of new physics, in particular at CERN LEP and Fermilab Tevatron colliders.

Abstract:
An effective Lagrangian for the technidilaton and its interactions with matter is constructed. Properties of the technidilaton are compared with those of the Higgs boson. Technidilaton decays and production channels are investigated. Main technidilaton decays are suppressed compared to the Higgs boson and the most important production mechanism is due to gluon fusion. Prospects for technidilaton production and detection at e+e− colliders and SSC are examined. LEP 1, LEP 2 and SSC can find or rule out a technidilaton with a mass up to 10 GeV, 40 GeV and 230 GeV respectively.

Abstract:
We have investigated some phenomenological aspects of an SU (2) × U (1) scenario where scalars belonging to arbitrary representations of SU(2) are involved in electroweak symmetry breaking. The resulting interaction terms are derived. Some constraints are obtained on the arbitrary scalar sector from the requirement of tree-level unitarity in longitudinal gauge boson scattering. We also show that there is a remarkable complimentarity between the constraints on a general structure from the ρ parameter and those from precision measurement of the [Formula: see text] vertex. Finally, some salient features about the production of such Higgs bosons in e+e− collision are discussed.

Abstract:
By analogy with the low energy QCD effective linear sigma model, we construct a standard model effective potential based entirely on the requirement that the tree level and quantum level trace anomalies must be satisfied. We discuss a particular realization of this potential in connection with the Higgs boson mass and Higgs boson effective couplings to two photons and two gluons. We find that this kind of potential may describe well the known phenomenology of the Higgs boson.

Abstract:
The new particle recently discovered at the Large Hadron Collider has properties compatible with those expected for the Standard Model (SM) Higgs boson. However, this does not exclude the possibility that the discovered state is of non-standard origin, as part of an elementary Higgs sector in an extended model, or not at all a fundamental Higgs scalar. We review briefly the motivations for Higgs boson scenarios beyond the SM, discuss the phenomenology of several examples, and summarize the prospects and methods for studying interesting models with non-standard Higgs sectors using current and future data.

Abstract:
We present the phenomenology of the low scale U(1)B–L extension of the standard model and its implications at LHC. We show that this model provides a natural explanation for the presence of three right-handed neutrinos and can naturally account the observed neutrino masses and mixing. We study the decay and production of the extra gauge boson and the SM singlet scalar (heavy Higgs) predicted in this type of models. We find that the cross sections of the SM-like Higgs production are reduced by ~ 20% – 30%, while its decay branching ratios remain intact. The extra Higgs has relatively small cross sections and the branching ratios of Z′ → l+l− are of order ~ 20% compared to ~ 3% of the SM results.

Abstract:
Suite à la découverte du boson de Higgs en Juin 2012 au Large Hadron Collider, l’accélérateur de particules situé à la frontière franco-suisse, l’étude du secteur scalaire des particules élémentaires a connu un regain d’intérêt. En particulier, le boson de Higgs étant une particule clef au sein du Modèle Standard des particules, les expérimentateurs étudient ses propriétés avec beaucoup de soin.Le Modèle Standard, dont le but est de décrire les interactions entre particules élémentaires, n’est cependant pas une théorie complète. En effet, en plus de quelques problèmes d’ordre théorique, certains phénomènes observés expérimentalement ne peuvent pas être expliqués par ce modèle. Les théoriciens en physique des particules cherchent donc à établir une nouvelle théorie venant le compléter et permettant d’expliquer pleinement les observations expérimentales.Cette thèse est axée sur l’étude du secteur scalaire de modèles au-delà du Modèle Standard des particules. J’ai plus particulièrement travaillé sur un modèle à deux doublets de Higgs – modèle purement effectif mais qui peut être inclus dans d’autres théories plus abouties – ainsi que sur un modèle construit comme une combinaison entre les théories déjà très proches de techicouleur et de Higgs composites, et ce dans le cas particulier d’une brisure de symétrie SU (4) ? Sp(4). J’ai étudié ce dernier modèle d’un point de vue effectif mais la théorie complète est capable depallier un certain nombre des limitations du Modèle Standard.Chacun de ces modèles inclut un secteur scalaire plus riche que celui du Modèle Standard et contient au moins une particule pouvant être assimilée au boson de Higgs découvert au LHC. J’ai réalisé l’étude phénoménologique de chacun de ces modèles et les ai confrontés à des contraintes tant théoriques qu’expérimentales – en particulier celles obtenues grâce aux études les plus récentes, portant sur le boson de Higgs et sur de potentielles particules scalaires additionnelles, réalisées par les équipes du LHC. Cela m’a permis de contraindre les paramètres libres des modèles et en particulier de restreindre les valeurs possibles pour la masse des autres particules scalaires, permettant de mieux cibler les zones où ces nouvelles particules, si elles existent, pourraient être détectées au LHC.Ces deux théories, bien que très contraintes par les données expérimentales, ne sont toujours pas exclues par les contraintes expérimentales les plus récentes
Following the discovery of the Higgs boson in June 2012 at the Large Hadron Collider, the particle collider located beneath the France-Switzerland border, interest in the study of the scalar sector in elementary particle physics significantly increased. In particular, as the Higgs boson plays a very special role in the Standard Model of particle physics, experimentalists study its properties with great care.The goal of the Standard Model is to describe the interactions between elementary particles. However the theory is not quite complete. Indeed, in addition to some purely theoretical problems, a number of experimental observations cannot be explained by the Standard Model. Theorists are therefore looking for a more comprehensive theory able to fully explain the observations.This thesis is based on the study of the scalar sector of two different extensions of the Standard Model of particle physics. I have worked on the Two-Higgs Doublet Model – this model is purely effective but can be included in more comprehensive theories – as well as on a model based on a combination of Technicolor and Composite Higgs theories in the framework of the SU (4) ? Sp(4) symmetry breaking pattern. I studied the latter via an effective approach but the full theory is able to get rid of some of the pitfalls of the Standard Model.These two models include a scalar sector that is richer than the one found in the Standard Model and contain at least one particle which can be assimilated to the Higgs boson discovered at the LHC.I performed a phenomenological study for these two models and tested them against both theoretical and experimental constraints. In particular I used the latest studies on the 125 GeV Higgs boson and on possible additional scalars performed by the ATLAS and CMS collaborations. The application of all these constraints drastically reduced the available parameter space of the two models. In particular it narrowed the possible mass range of the additional scalars, allowing to know more accurately where to search them experimentally in order to prove or rule out their possible existence.As of today the two theories I worked on are still not excluded by the latest experimentaldata

Abstract:
After a brief description of the Standard Model of Particle Physics, we introduce the Hierarchy Problem and its possible resolutions. Among several possibilities we choose two protection mechanisms that realize a Natural Fermi scale: Composite Higgs and Supersymmetry. Our aim is to consider realistic natural models for the Fermi scale and compare them with the experimental data coming (mainly) from precision measurements. In the case of Composite Higgs, we discuss the ne tuning needed to realize a successful electro-weak symmetry breaking and accommodate a 125 GeV Higgs. Composite Higgs can naturally explain such light mass if new coloured fermions with the same quantum numbers of the top are below or at 1000 GeV. Direct searches are starting to probe the natural region of this kind of models. However, there are strong constraints on this picture coming from electro-weak and avour tests. Although non trivially, it is possible to satisfy the bounds if appropriate representations of the composite fermions are chosen and an approximate U(2)3 flavour symmetry is at work. The Minimal Supersymmetric Standard Model (MSSM) experiences a significant finetuning because a 125 GeV Higgs boson is too heavy to be obtained naturally. After a brief review of the MSSM and a discussion of its Higgs sector, we consider the Next-to-Minimal Supersymmetric Standard Model (NMSSM). The NMSSM provides a 125 GeV Higgs boson with milder tuning and it also mitigates naturalness upper bounds on stops and gluinos, which start to be strongly constrained from below by direct searches. Another relevant aspect of the NMSSM is the suggestion that the lightest new particles could be the CP-even scalars of its extended Higgs sector. This possibility can be efficiently constrained from the measurements of the Higgs mass and branching ratios at LHC. In many cases the Higgs fit is an important constraint, competitive with direct searches. When these constraints are absent we outline possible strategies for future experimental searches. We conclude with a brief summary and comment on the relative importance of electroweak and Higgs precision measurements in the models discussed in the thesis.

Abstract:
In this thesis two different aspects of Standard Model Higgs boson phenomenology at hadron colliders are addressed. A precise theoretical knowledge of production cross sections is needed in order to assist in the Higgs boson search efforts of the experimental community. Consequently, the next-to-leading-order electroweak corrections to Higgs boson production in association with a vector boson at hadron colliders have been calculated. Significant corrections were found, and theoretical uncertainties were analysed. In addition to production cross sections, a deep knowledge of background processes is also needed, especially at hadron colliders. The gluon-induced contributions to offshell W-boson pair production have been calculated. The invariant amplitude has been used to calculate the contribution from gluon initiated processes to the non-resonant W-boson pair production background to the Higgs boson search channel at the CERN LHC. These contributions are evaluated in the approximation of massless quarks circulating the loops. These results were used to study the effect of experimental cuts proposed to increase the signal to background ratio of the above mentioned search channel.

The Higgs sector is the last part of the standard model of particle physics where we lack directexperimental results. Many extensions to the standard model describe an extended Higgs sector,often containing charged scalar bosons in addition to the standard model’s neutral Higgs boson.The H+WZ vertex can be used to distinguish between different non-standard Higgs sectors, andto measure the mass of the charged Higgs boson. In this report I will examine a promising searchchannels at the LHC and look at its phenomenology using monte carlo simulations.

Abstract:
After a long history of searches, a Higgs boson H was discovered by the ATLAS and the CMS experiments at the Large Hadron Collider (LHC) in 2012. Its properties fit well the ones predicted by the Standard Model (SM) of particle physics. However, the SM can not explain other established properties of Nature, such as the existence of Dark Matter. For this reason, models beyond the SM should be considered. Such models often predict the existence of several Higgs bosons and this thesis explores some of those models. In particular, the possibility to discover a charged Higgs boson, which would be a clear sign of physics beyond the SM, is studied. A commonly studied extension of the SM is the framework of two-Higgs-doublet models (2HDMs), where there are five Higgs bosons. By confronting the parameter spaces of some 2HDMs with publically available data from the LHC, the prospects for finding the 2HDM Higgs bosons is presented through the calculation of production cross sections and decay branching ratios in various channels. A new kind of 2HDM, called the Stealth Doublet Model is presented and the properties of the Higgs bosons are studied. In this model, it is shown that in particular the properties of the charged Higgs boson H± have new features not exhibited in earlier studied models. Within the parameter space compatible with the LHC results, the production cross section for H± can be sizeable enough to be experimentally observed. Finally, the discovery prospects at the LHC, for a H± in the pp → tH± process, with the decays H± → HW± and H → bb, is studied in various models beyond the Standard Model. It is shown that for the supersymmetric models, this channel is beyond the discovery reach of the LHC. In some of the other studied models, in particular the Aligned 2HDM, the situation is improved and the channel is feasible.

Abstract:
Avec la découverte en juillet 2012 par les collaborations CMS et ATLAS d'un nouveau scalaire, aux propriétés similaires à celles d'un boson prédit plus de 50 ans auparavant, la phénoménologie au-delà du modèle standard (SM) a fait un grand pas. En effet, la découverte de cette pièce manquante du puzzle électrofaible a rendu certains modèles impossibles, tout en renforçant la crédibilité du SM. Cependant, on sait que le SM n'est pas le mot de la fin, car certaines de ses prédictions ne s'accordent pas avec les expériences, et ce boson est donc vu comme une porte vers de nouveaux secteurs de la physique. Après une introduction au SM et aux statistiques de la physique des particules, nous présenterons un paramétrage des couplages mesurés au LHC, afin de contraindre, via ces couplages, des modèles de physique au-delà du SM, plus fondamentaux. Ce paramétrage, s'intéressant particulièrement aux couplages à boucles, permettrait de lever une corrélation existant entre les paramètres actuellement utilisés. Nous étudierons ensuite la possibilité d'existence d'un scalaire, plus léger que celui observé, et ayant échappé aux recherches passées, et de sa recherche au LHC à l'aide de ce paramétrage. Nous donnerons des exemples de paramètres faisant apparaître un tel scalaire, dans le 2HDM et le NMSSM. Enfin, nous verrons que le scalaire peut influencer la production d'une paire de bosons de jauge faible, et qu'à l'aide de notre paramétrage, l'analyse de ce processus peut être utilisée de manière cohérente avec les mesures au pic de masse pour contraindre ces couplages. Nous finirons avec quelques limites de cette approche, ainsi que des propositions d'améliorations
With the discovery of a new particle in July 2012 by the CMS and ATLAS experiments, with properties resembling those of a boson predicted about 50 years earlier by theorists, the search for physics outside of the standard model of particle physics (SM) has made a big step. Indeed, the existence of this piece of the electroweak symmetry breaking proved wrong many theories, while giving more credit to the SM. However, because of some observations it fails to match, we know the SM cannot be the final word, and it is hoped that the study of this new particle will be a path to new sectors of physics. After a brief description of the SM and of the statistics of particle physics, we will present a way to parametrise the couplings measured at CERN, in order to constrain, through these couplings, more fundamental models describing physics beyond the standard model. This parametrisation, focusing on loop-induced couplings, would allow to lift a correlation existing between parameters currently used by experimentalists. We will then study the feasibility of a search for another scalar, lighter than the one discovered and which would have escaped previous searches, through the use of the same parametrisation. In two models, the 2HDM and the NSSSM, values of parameters yet unconstrained are shown.Finally, we will see that this scalar can also influence the joint production of two weak gauge bosons. We will show that the analysis of this process can be used in a coherent manner with on-shell Higgs measurements to constrain its couplings through our parametrisation. We will then end with a brief look at some limitation of this approach, before suggesting ways to overcome them

Abstract:
For more than 30 years the Standard Model has been the theoretical foundation for particle physics. The theory has been verified successfully by experimental tests. Its biggest shortcoming is the non-discovery of the Higgs boson,responsible for giving the other particles masses. Despite its success there are hints that the Standard Model is not the complete theory and many extensions of it, such as supersymmetry, have been proposed. Extended theories often predict the existence of a charged Higgs boson and its detection will be a clear sign of physics beyond the Standard Model. The main focus in this thesis is on various phenomenological aspects of the charged Higgs boson. For favorable mass and couplings direct detection is shown to be possible at the Large Hadron Collider in production with an associated W boson. It is also shown how a light charged Higgs can have measurable effects on spin correlations in decays of pair-produced top quarks. The charged Higgs boson can also be seen indirectly, in for example B-meson decays, which can be used to put constraints on its mass and fermion couplings. Exclusion limits in two supersymmetric models are given together with a comparison with the discovery potentials for the LHC experiments. A tool for calculating properties, such as masses and decays, of both charged and neutral Higgs bosons in the Two-Higgs-Doublet Model is also presented. B-meson decays can also be used to test aspects of the strong interaction. Part of this thesis deals with improving and applying phenomenological models to B-meson decays. Although these models are not derived from first principles, their success shows that they capture important features of non-perturbative strong interactions.

Abstract:
Il y a près de deux décennies, l'utilisation des modèles à dimensions supplémentaires pour résoudre le problème de hiérarchie des théories de jauge a reçu beaucoup d'attention, au travers d'élégantes propositions : des dimensions supplémentaires (DS) étendues et plates - le modèle d'Arkani-Hamed-Dimopoulos-Dvali, ou ADD - ainsi que des DS courbées - le modèle de Randall-Sundrum, ou RS. Dans cette thèse, nous discutons plusieurs modèles inspirés de tels scénarios extra-dimensionnels. Pour commencer, nous introduisons des éléments-clés de la théorie des champs en cinq dimensions, et nous montrons comment de tels scénarios apportent une réponse au problème de hiérarchie. Ensuite, dans une première partie, nous adoptons une approche ``de bas en haut'' et étudions plusieurs modèles contenant des fermions vectoriels (FV), prédits génériquement dans les modèles de DS. Nous montrons qu'en ajoutant des quarks vectoriels (QV) au Modèle Standard (MS), on peut expliquer en même temps les anomalies (i) d'asymétrie avant-arrière des quarks b, mesurée au Large Electron-Positron collider (LEP) et (ii) de section efficace de production de tth mesurée au Large Hadron Collider (LHC). En utilisant des rapports de taux de désintégration du Higgs, nous estimons aussi la sensibilité du LHC amélioré, le LHC à haute luminosité, à la présence de QV. Puis nous considérons un modèle à deux doublets de Higgs (2HDM), accompagné de leptons vectoriels (LV) pour expliquer le mystérieux excès à 750 GeV observé au LHC fin 2015. Dans un modèle similaire, nous expliquons également l'abondance de matière sombre (MS) dans l'Univers, notre candidat pour la MS étant un LV neutre, stabilisé par une symétrie Z2 appropriée. Par la suite, dans une deuxième partie de la thèse, nous nous penchons sur le scénario plus concret des DS courbées dotées d'une symétrie custodiale dans l'espace cinq-dimensionnel, qui protège le modèle vis-à-vis de larges corrections électrofaibles. Dans ce cadre, nous interprétons tout d'abord la bosse à deux bosons observée à 2 TeV au LHC comme une superposition de bosons de jauge de Kaluza-Klein, produits en canal s. Dans un deuxième temps, nous étudions la phénoménologie du secteur scalaire du modèle susdit, qui mêle le Higgs et le radion. En particulier, nous estimons la sensibilité du LHC et d'un futur collisionneur électron-positron (l'International Linear Collider - ILC) à l'existence d'un radion, via la production de celui-ci en association avec un boson Z
Almost two decades ago, the paradigm of extra-dimensional models addressing the gauge hierarchy problem attracted much attention through the elegant proposals of large, flat extra dimensions (EDs) - the Arkani-Hamed-Dimopoulos-Dvali or ADD model - and warped EDs - the Randall-Sundrum or RS model. In this thesis, we discuss several models inspired from such extra-dimensional scenarios. We start by introducing some key elements of field theory in five space-time dimensions and showing how such scenarios provide a solution to the hierarchy problem. Afterwards, in a first part of this work, we adopt a bottom-up approach and study several models containing Vector-Like Fermions (VLFs), which are typically predicted in ED frameworks. We show how adding Vector-Like Quarks (VLQs) to the Standard Model (SM) allows one to simultaneously explain the anomalies in the (i) b-quark forward-backward asymmetry measured at the Large Electron-Positron collider (LEP) and (ii) the tth production cross section measured at the Large Hadron Collider (LHC). Using the so-called Higgs decay ratios, we also estimate the sensitivity of the upgraded LHC, the High-Luminosity LHC, to the presence of VLQs. Then, we consider a Two-Higgs Doublet Model (2HDM) extended with Vector-Like Leptons (VLLs) in order to fit the mysterious 750 GeV excess observed at LHC in late 2015. Within a similar model, we also explain the Dark Matter (DM) abundance in the Universe, our DM candidate being a neutral VLL, which is rendered stable by a suitable Z2 symmetry. Later on, in a second part of the thesis, we focus on the more concrete warped ED scenario endowed with a bulk custodial symmetry, which protects the model from large electroweak (EW) corrections. In this framework, we first interpret the 2 TeV diboson bump observed at LHC in 2015 as a superposition of Kaluza-Klein (KK) gauge bosons produced in the s-channel. Afterwards, we study the phenomenology of the mixed Higgs-radion scalar sector of the aforementioned model. In particular, we estimate the sensitivity of the LHC and of a future electron-positron collider (the International Linear Collider - ILC) to the existence of a radion via its production in association with a Z boson
