Abstract:
Known as one of the most hopeful fields to find the new particle—Higgs bosons and become even more important after it is proved by Higgs. Higgs and his colleagues further improve their observation of the Higgs Bosons through the Higgs mechanism. This paper will show the basic properties of the Higgs bosons, and some machines of the Higgs bosons. The spontaneous symmetry breaking, and the Higgs mechanism have also been introduced due to their necessity for the Higgs boson. This paper will be an introduction for anyone who is interested in this field.

Abstract:
Besides the SM-like Higgs boson h, the left–right twin Higgs (LRTH) model predicts the existence of three additional Higgs bosons: one neutral Higgs ϕ0and a pair of charged Higgs bosons ϕ±. In this paper, we focus on the study of the triple Higgs production at the ILC, i.e. e+e-→ϕ0ϕ+ϕ-and e+e-→hhϕ0. We present the production cross-sections and the distributions of the various observables, such as, the distributions of the energy and the transverse momenta of neutral and charged Higgs bosons, the differential cross-section of the invariant mass of final Higgs bosons pair, and the production angle distributions of neutral Higgs boson and charged Higgs boson. Our numerical results show that, for the processes e+e-→ϕ0ϕ+ϕ-and e+e-→hhϕ0, the production rates are at the level of 10-1fb with reasonable parameter values while the resonance production cross-section can be significantly enhanced and reach several tens fb. The signatures for signals and corresponding standard model backgrounds are also investigated for the decay mode [Formula: see text].

Abstract:
The discovery of the Higgs boson in 2012 provided confirmation of spontaneous electroweak symmetry breaking as the mechanism by which fundamental particles gain mass and thus completed the Standard Model of particle physics. Additionally, it opened a new approach to searching for potential new particles. Many beyond the Standard Model theories predict new heavy particles that couple to the Higgs boson, leading to a resonant production mode of Higgs boson pairs. Other theories extend the Higgs sector by introducing additional scalar bosons that differ from the observed Higgs boson only by mass. The ATLAS and CMS Collaborations have searched for evidence of such processes using s=13 TeV Run 2 proton-proton collision data at the Large Hadron Collider. This review article summarizes the latest experimental results from searches for resonant production of pairs of Higgs bosons or additional Higgs-like scalar bosons at ATLAS and CMS.

Abstract:
Extended scalar sectors appear in various extensions of the Standard Model of particle physics, such as supersymmetric models. They are also generic extensions of the Standard Model and can address a number of its shortcomings. Direct searches for additional Higgs bosons and measurements of the 125-GeV Higgs boson, both of which provide insights into the different possible sectors, are carried out at the LHC. This review gives an overview of searches for the additional Higgs bosons and their implications for different models. The discussed analyses comprise searches for neutral and charged Higgs bosons that decay in various final states. In addition, the review summarizes the constraints from precision measurements, including in particular the observed couplings of the 125-GeV Higgs boson. While several models naturally incorporate a Higgs boson with couplings that are similar to the ones in the Standard Model, the measurements of the 125-GeV Higgs boson provide constraints on all considered extensions.

Abstract:
We review the techniques and results of the searches for the Higgs boson performed by the two Tevatron collaborations, CDF and DØ. The Higgs boson predicted by the Standard Model was sought in the mass range 90 GeV < mH < 200 GeV in all main production modes at the Tevatron: gluon–gluon fusion, WH and ZH associated production, vector boson fusion, and [Formula: see text] production, and in five main decay modes: [Formula: see text], H→τ+τ-, H→WW(*), H→ZZ(*) and H→γγ. An excess of events was seen in the [Formula: see text] searches consistent with a Standard Model Higgs boson with a mass in the range 115 GeV < mH < 135 GeV . Assuming a Higgs boson mass of mH = 125 GeV , studies of Higgs boson properties were performed, including measurements of the product of the cross section times the branching ratio in various production and decay modes, constraints on Higgs boson couplings to fermions and vector bosons, and tests of spin and parity. We also summarize the results of searches for supersymmetric Higgs bosons, and Higgs bosons in other extensions of the Standard Model.

Abstract:
The unitarity of the mixing matrix of the charged Higgs bosons, and the orthogonality of the mixing matrix of the neutral Higgs bosons, are used to derive upper bounds on the values of general CP-violating expressions. The bounds are independent of the total number of Higgs fields in any specific model. They allow us to relax the usual assumption of only one Higgs boson being light. It is natural that the CP violation in the exchange of neutral Higgs bosons between bottom quarks be particularly large.

Abstract:
The Higgs sector of supersymmetric models with an additional SU (2)× U (1)Y singlet or an additional pair of Higgs doublet superfields is investigated. It is shown that in the model with a Higgs singlet bounds on Higgs boson masses are considerably weaker than in the minimal supersymmetric model; in particular, all neutral scalars can be heavier than about 150 GeV or lighter than [Formula: see text], whereas the mass of the charged Higgs boson is essentially unconstrained. The four doublet model resembles the minimal model more closely; in particular, the bounds for the heaviest and lightest neutral scalar and the heaviest charged Higgs boson are unaltered. In this model, many relations between masses of different Higgs bosons can be found; 44 of the 66 possible decays of one Higgs boson into another Higgs boson plus a real W or Z boson are kinematically forbidden. It is also shown that in both models, the lightest neutral scalar becomes indistinguishable from the standard model Higgs boson if all other Higgs bosons of the model are much heavier than Mw.

Abstract:
The investigation of the dynamics responsible for electroweak symmetry breaking is one of the prime tasks of experiments at present and future colliders. Experiments at the Tevatron [Formula: see text] Collider and at the CERN Large Hadron Collider (LHC) must be able to discover a Standard Model Higgs boson over the full mass range as well as Higgs bosons in extended models. In this review, the discovery potential for the Standard Model Higgs boson and for Higgs bosons in the Minimal Supersymmetric extension is summarized. Emphasis is put on those studies which have been performed recently within the experimental collaborations using a realistic simulation of the detector performance. This includes a discussion of the search for Higgs bosons using the vector boson fusion mode at the LHC, a discussion of the measurement of Higgs boson parameters as well as a detailed review of the MSSM sector for different benchmark scenarios. The Tevatron part of the review also contains a discussion of first physics results from data taken in the ongoing Run II.

Abstract:
We investigate an extension of the Standard Model with one additional triplet of scalar bosons. Altogether, the model contains four Higgs bosons. We analyze the associated production of the doubly charged scalar with the Standard Model gauge bosons and the remaining Higgs bosons of the model, which are: the light (SM) and heavy neutral scalars and a singly charged scalar. We estimate, in the context of the present (HL–LHC) and future (FCC–hh) hadron colliders, the most promising processes in which a single produced doubly charged Higgs boson is involved.

Resumo: 0 Modelo Padrão é, hoje em dia, a melhor formulação teórica para a descrição das interações eletrofracas. 0 acordo entre resultados experimentais e previsões teóricas é expressivo para acoplamentos entre bósons vetoriais e férmions. Porém, possuímos poucas informações sobre o bóson de Higgs, remanescente do mecanismo de quebra de simetria eletrofraca responsável pela geração das massas dos férmions e dos bósons vetoriais. Neste trabalho procuramos explorar alternativas para os acoplamentos do bóson de Higgs aos demais bósons da teoria através do uso de lagrangeanas efetivas. Examinamos as consequências destas novas interações em diversas reações envolvendo a produção e decaimento do bóson de Higgs em colisões elétron-pósitron e hadrônicas. 0 estudo dessas reações nos permite impor vínculos sobre as constantes de acoplamento destas novas interações, os quais são comparados com os limites experimentais das constantes de acoplamento da parametrização convencional dos auto-acoplamentos entre os bósons vetoriais IVWZ e W'gama'.
Abstract: The Standard Model is the best theoretical framework which describes the elec- troweak interactions. The agreement between experimental data and theoretical predictions is spectacular for the fermion-vector boson couplings. However, we have few information concerning the electroweak symmetry breaking sector of the theory. In this Work we explore diíferent possibilities for the couplings among the Higgs boson and the vector bosons of the theory through the use of the effective lagrangian formalism. We examine the consequences of these new interactions in several re- actions involving the Higgs boson production and decay at electron-positron and hadronic collisions. We analyze these reactions in order to impose bounds on the coupling constants of these new interactions. These bounds are compared with the experimental limits on the usual parametrization of the anomalous WWZ and WW'gama'

Abstract:
La thèse décrit une étude de l'état final en paire de leptons τ dans le mode de désintégration semi-leptonique en muons et hadrons en utilisant des données proton-proton collisions à une énergie de centre de masse de 7 TeV avec le détecteur CMS au CERN Large Hadron Collider. La performance de l'algorithme de reconstruction et d'identification des leptons τ est étudiée en utilisant un échantillon de données de collisions proton-proton à √s = 7 TeV, ce qui correspond à une luminosité intégrée de 36 pb⁻¹. Les leptons τ qui se désintègrent en un seul hadron chargé, avec ou sans hadrons neutres sont reconstruits à l'aide de la technique dite du flot de particules pour la reconstruction des objets en utilisant un nouvel algorithme adapté aux leptons τ et appelé le Hadrons Plus Strips (HPS) qui utilise le trajectographe et le calorimètre électromagnétique de CMS. L'efficacité de l'algorithme de reconstruction est mesurée en utilisant les leptons τ produits lors de la désintégration de bosons Z. Le taux de mauvaise identification de leptons τ se désintégrant de manière hadronique pour les jets produits en association avec un boson W est également déterminé. La première mesure inclusive de production Z→ττ dans les collisions pp au le LHC est présentée dans les états finals muon+jets en utilisant un échantillon de données de 36 pb⁻¹. La section efficace mesurée est en bon accord avec les prédictions QCD à l'ordre doublement suivant l'ordre dominant (NNLO). Après avoir identifié le boson Z dans le mode de désintégration di-τ, une recherche inclusive de bosons de Higgs neutres du modèle supersymétrique standard minimal (MSSM) dans les collisions pp est réalisée à une énergie dans le centre de masse de 7 TeV. Les résultats sont basés sur un échantillon de données correspondant à une luminosité intégrée de 36 pb⁻¹ et de 4,6 fb⁻¹ enregistré par l'expérience CMS dans l'année 2010 et 2011 respectivement. La recherche utilise les désintégrations de bosons de Higgs en paire de leptons τ. Aucun excès n'est observée dans le spectre de masse invariante de paires de leptons τ. Les limites supérieures sur le produit de la section efficace de production de boson de Higgs par le rapport de branchement de la désintégration en paire de leptons τ en fonction de la masse du boson de Higgs pseudoscalaire permettent de donner des limites strictes dans l'espace des paramètres du MSSM
The thesis describes a study of the τ-pair final state in the semi-leptonic decay mode into muon and hadrons using proton-proton collisions data at a center-of-mass energy of 7 TeV using the CMS detector at the CERN Large Hadron Collider. The performance of τ-lepton reconstruction and identification algorithm is studied using a data sample of proton-proton collisions at √s = 7 TeV, corresponding to an integrated luminosity of 36 pb⁻¹. The τ leptons that decay into one charged hadron with or without the association of neutral hadrons is reconstructed using Particle-Flow object reconstruction technique with a novel τ identification algorithm called the Hadron Plus Strips (HPS) algorithm in the CMS tracker and electromagnetic calorimeter. The reconstruction efficiency of the algorithm is measured using τ leptons produced in Z-boson decays. The hadronically decaying τ lepton misidentification rate for jets produced in association with a W boson is also determined. The first measurement of inclusive Z→ττ production in pp collisions at the LHC is presented in muon+hadrons final state using a data sample of 36 pb⁻¹. The measured cross-section is in good agreement with the next-to-next-to-leading order (NNLO) QCD prediction. After establishing the Z boson in di-τ decay mode, an inclusive search for neutral minimal supersymmetric standard model (MSSM) Higgs bosons in pp collisions is performed at a center-of-mass energy of 7 TeV. The results are based on a data sample corresponding to an integrated luminosity of 36 pb⁻¹ and 4.6 fb⁻¹ recorded by the CMS experiment in the year 2010 and 2011 respectively. The search uses decays of the Higgs bosons to τ pairs. No excess is observed in the τ-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross-section times the branching fraction to τ pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent bounds in the MSSM parameter space

Abstract:
L’étude des propriétés du boson de Higgs représente une excellente opportunité pour la recherche de Nouvelle Physique. En particulier, sa masse est mesurée avec une précision impressionnante, de l’ordre de 0.1%, tandis qu’elle est aussi prédite par certains modèles au-delà du Modèle Standard, notamment les modèles supersymétriques. Le but de cette thèse est de faire avancer le calcul des corrections radiatives aux masses des scalaires dans les modèles au-delà du Modèle Standard, ainsi que l’automatisation de ces calculs, afin d’établir ou d’améliorer les limites sur les couplages entre la Nouvelle Physique et le boson de Higgs. Nous calculons d’abord les corrections dominantes à deux boucles, de la forme O(alpha_s alpha_t), aux masses des scalaires neutres dans les modèles supersymétriques à jauginos de Dirac. Ensuite, nous montrons comment surmonter la Catastrophe des Bosons de Goldstone, un cas de divergences infrarouges dues aux bosons de Goldstones de masses nulles qui affecte les calculs de potentiels effectifs, d’équations « tadpoles » et d’énergies propres, en adoptant un schéma de renormalisation « on-shell » pour les masses des bosons de Goldstone. Nous illustrons la mise en œuvre numérique de notre solution dans le programme SARAH, et finalement, nous considérons le comportement aux hautes énergies de modèles non-supersymétriques avec des secteurs scalaires étendus
The Standard Model-like Higgs boson provides an excellent setting for the indirect search of New Physics, through the study of its properties. In particular its mass is now measured with an astonishing precision, of the order of 0.1%, while being predicted in some models of Beyond the Standard Model (BSM) Physics, such as supersymmetric (SUSY) models. The main purpose of this thesis is to push further the calculation of radiative corrections to Higgs boson masses in BSM models, as well as the automation of these calculations, in order to set or improve constraints on New Physics coupling to the Higgs boson. A first chapter is devoted to the computation of the leading two-loop O (alpha_s alpha_t) corrections to neutral scalar masses in SUSY models with Dirac gauginos. Then, we show to address the Goldstone Boson Catastrophe -- a case of infra-red divergences due to massless Goldstone bosons that plague the calculation of effective potentials, tadpole equations, and self-energies -- in the context of general renormalisable field theories, by adopting an on-shell renormalisation scheme for the Goldstone masses. Afterwards, we illustrate the numerical implementation of our solution to the Goldstone Boson Catastrophe in the public tool SARAH. Finally, in a last chapter, we consider the high-scale behaviour of non-supersymmetric models with extended Higgs sectors

Abstract:
En utilisant les outils de Monte Carlo et les données de test en faisceau, la performance d’un détecteur au futur collisionneur linéaire international a été étudiée. La contribution de cette thèse porte sur deux parties; d’une part sur une mesure de précision de la masse du boson Higgs et de la section efficace de la production avec le processus e+e  HZ où le boson Z se désintègre en paire  et d’autre part sur une analyse des données de test en faisceau de la collaboration CALICE (CAlorimeter for Linear Collider Experiment). Pour un Higgs de 120GeV, nous avons obtenu une précision de 38. 4MeV sur la masse de Higgs et de 5% sur la section efficace en choisissant une énergie dans le centre de masse optimale de 230 GeV et avec une luminosité intégrée de 500 fb-1. Ces résultats sont indépendants d’un modèle de Higgs donné puisque aucune information sur la désintégration du Higgs n’a été utilisée dans l’analyse. Si on suppose que le Higgs est celui du modèle standard ou il se désintègre principalement en particules invisibles, la précision peut être améliorée de façon significative (29MeV pour la masse et 4% pour la section efficace). Pour l’analyse des données de test en faisceau, mon travail concerne deux aspects. Premièrement une vérification sur la qualité des données en temps quasi réel et deuxièmement une mesure précise sur la résolution angulaire d’une gerbe électromagnétique dans le calorimètre prototype utilisé dans le test en faisceau. Le but pour la vérification de la qualité des données est de détecter des problèmes éventuels sur l’ensemble du détecteur y compris l’électronique, le système de haute tension et d’acquisition, et de classer des différentes données pour faciliter les analyses offlines. Pour déterminer la résolution angulaire du calorimètre électromagnétique, nous avons développé un algorithme qui est basée uniquement sur le dépôt d’énergie dans différentes cellules produites par le faisceau d’électrons sans utilisant l’information du détecteur de trace devant le calorimètre. Celle-ci est importante pour pouvoir identifier le composant neutre d’un jet. Nos résultats montrent que la dépendance de la résolution angulaire en énergie du faisceau est similaire à celle de la résolution en énergie et peut être décrite par 80 mrad/√(E/GeV)
Utilizing Monte Carlo tools and test-beam data, some basic detector performance properties are studied for the International Linear Collider (ILC). The contributions of this thesis are mainly twofold, first, a study of the Higgs mass and cross section measurements at the ILC (with full simulation to e+e  HZ  H channel and corresponding backgrounds); and second, an analysis of test-beam data of the CAlorimeter for Linear Collider Experiment (CALICE). For a 120GeV Higgs particle, setting the center-of-mass energy to 230GeV and with an integrated luminosity of 500fb-1, a precision of 38. 4MeV is obtained in a model independent analysis for the Higgs boson mass measurement, while the cross section can be measured to 5%; if we make some further assumptions about the Higgs boson’s decay, for example a Standard Model Higgs boson or a Higgs boson with a dominant invisible decay mode, the measurement results can be improved by 25% (achieving a mass measurement precision of 29MeV and a cross section measurement precision of 4%). For the CALICE test-beam data analysis, our work is mainly focused upon two aspects: data quality checks and the track-free ECAL angular resolution measurement. Data quality checks aim to detect strange signals or unexpected phenomena in the test-beam data so that one knows quickly how the overall data taking quality is. They also serve to classify all the data and give useful information for later offline data analyses. The track-free ECAL angular resolution algorithm is designed to precisely measure the direction of a photon, a very important component in determining the direction of neutral components in jets. We found that the angular resolution can be well fitted as a function of the square root of the beam energy (in a similar way as for the energy resolution) with a precision of approximately 80mrad/√(E/GeV)

Abstract:
Dans ce travail, les potentialités du détecteur ATLAS pour l'identification des jets issus de quark beau sont étudiées. L'étiquetage topologique, basé sur le paramètre d'impact des traces chargées, est utilisé. Une bonne identification de ces jets sera très précieuse au LHC, en particulier durant les premières années de fonctionnement pour mettre en évidence le cas échéant un boson de Higgs d'une masse comprise entre 80 GeV/c2 et 120 GeV/c2. Pour évaluer les performances dans ce domaine, un algorithme de recherche et reconstruction des traces chargées exploitant la simulation détaillée du détecteur interne d'ATLAS a été réalisé. La recherche est initiée dans les détecteurs à pixels. L'efficacité et la qualité de reconstruction assurent une bonne discrimination entre les jets b et les autres jets. Après simulation complète et reconstruction d'événements H->bbbar, H->gg, H->uubar, H->ssbar et H->ccbar (mH = 100 GeV/c2), les réjections moyennes des jets non-b pour une efficacité d'étiqueter les jets b de 50% sont: Rg = 39+-5 Ru = 60+-9 Rs = 38+-5 Rc = 9+-1 Les résultats de l'analyse des données prises lors de tests en faisceau des premiers prototypes de matrices de détecteurs à pixels en technologie résistante aux radiations justifient les potentialités de ce type de détecteur pour la recherche de traces et la mesure précise de leur paramètre d'impact.

In this thesis, I show my contribution to the search for the Standard Model Higgs Boson decaying into two tau leptons in the tlepthad sub-channel. I contributed to the different stages of this analysis. First, I worked on the development of the framework used to produce analysis files that contain the information necessary for this study. I also participated in the development of the framework used to introduce the predictions of the background for that channel, test the agreement between the predictionsand the ATLAS data, and on the production of files used in the final statistical analysis. I also worked on the statistical model, which takes into account the statistical and systematic errors to extract a measure of the signal strength for the Higgs coupling channel to leptons. My contribution to the improvement of reconstruction of a hadronic tau, using algorithms that identify photon conversion traces from the decay of neutral pions, is also detailed

Abstract:
AbstractThe basic theoretical concepts motivating the hypothesis that dark matter may consist of ultralight spin-0 or spin-1 bosons are explored. The origin of bosons with masses ≪ 1 eV from spontaneous and explicit symmetry breaking is illustrated with examples. The origins and characteristics of nongravitational couplings or “portals” between ultralight bosons and Standard Model particles and fields are considered, with particular attention paid to the cases of the axion-photon and axion-fermion interactions. Theoretical motivations for the existence of ultralight bosons, besides as an explanation of dark matter, are examined, with particular focus on the Peccei-Quinn solution to the strong CP problem (resulting in the QCD axion) and a dynamical solution to the hierarchy problem (the “relaxion” hypothesis, based on a particular axion-Higgs coupling in the early universe). Mechanisms for non-thermal production of ultralight bosonic dark matter are examined.
