Preheating in new Higgs inflation
… resonance, the process is called preheating. New Higgs Inflation presumes that the Higgs field is the scalar field in question, involving a characteristic non-minimal "derivative" coupling. The equation of motion for the field evolves like a damped harmonic oscillator, so we expect it to oscillate …

Higgs family symmetry and supersymmetry
… building models of family symmetry that give the Higgs fields family structure. We construct several models, starting with 2 generation models then moving onto 3 generation models. These models are described sequentially in chapters 2 through 6. All of these models are supersymmetric and they did …

Measuring Higgs self-coupling at CMS
… (CMS) experiment's ability to characterize Higgs self-coupling through the ... channel. The effective cross-section for detecting ... events is computed by finding the fraction of simulated events that make it through selection cuts. These same cuts also are applied to simulated background …

Cosmology of hidden sector with Higgs portal
… gauge interactions, but couple directly to the Higgs field. We particularly focus on their relic particle density as a candidate for dark matter. For the case of hidden sector without a gauge field we have improved the accuracy of the bounds on the coupling constant and give bounds on the …

First evidence for vector boson fusion produced Higgs boson in the WW* decay channel and search for extended Higgs sector
… the particle is consistent the Standard Model Higgs boson within the uncertainty of the measurements. Individual observations of the Higgs boson production and decay channels are crucial in further confirming beyond a doubt that this is indeed the Standard Model Higgs boson. This thesis …

Refining the multi-field effects of Higgs inflation
… inclusion of multiple scalar fields in models of Higgs inflation produces observable departures from the single field case. I designed simulations to numerically solve the differential equations of motion in the Einstein frame governing the evolution of two nonminimally coupled fields in a quartic …

Higgs Effects in Neutrino Physics and Heavy Quark Systems
… work presents a study of the effects of multi-Higgs doublets on the properties of neutrino sector and heavy quark systems. The phenomenological implications of multi-Higgs models, which contain multi-Higgs doublets, in the neutrino and quark sector are discussed in this dissertation. The …

ΜΗΧΑΝΙΣΜΟΣ HIGGS ΓΙΑ ΑΒΕΛΙΑΝΕΣ ΘΕΩΡΙΕΣ ΒΑΘΜΙΔΑΣ ΣΕ ΧΩΡΟΧΡΟΝΙΚΟ ΠΛΕΓΜΑ
THE OBELIAN HIGGS MODEL IS STUDIED ON A SPACE-TIME LATTICE. THE MODEL EXHIBITS THREE PHASES, NAMELY COULOMB, HIGGS AND CONFINING PHASE. THE COLEMIN-WEINBERG MECHANISM IS SEEN TO OPERATE. THE EFFECTIVE POTENTIAL IS CALCULATED BY COUPLING THE SYSTEM TO EXTERNAL CURRENTS. IN THE HIGGS PHASE THERE …

Low energy consequences of some non-standard Higgs models
Little Higgs models offer an innovative solution of the naturalness problem of the Standard Model. These models contain new particles which cancel the quadratic divergences in the Higgs mass caused by the top, gauge and Higgs loops. These new particles contribute to loop induced interactions of the …

Spontaneous CP-Violation in Two Higgs Doublet Supersymmetric Models
… of spontaneous CP-breakdown in models with two Higgs doublets. General features of the phenomenon such as stability of the vacuum and the existence of a light axion are discussed. We investigate the feasibility of spontaneously broken CP in the minimal supersymmetric models - the MSSM and NMSSM. …

Symmetries of the scalar sector of multi-Higgs-doublet models
… in the Standard Model, the Brout- Englert-Higgs Mechanism predicts the existence of a scalar boson, whose discovery has been the main goal of the Large Hadron Collider. However, introducing this scalar boson does not provide the answer to all inadequacies of the Standard Model. Many …

New Aspects of Gauge-Boson Couplings and the Higgs Sector
… extensions. As an example we investigate Multi-Higgs-Doublet Models with respect to the stability of their potential and to spontaneous electroweak symmetry breaking. Further, two approaches to the model-independent parameterisation of new-physics effects in the gauge-boson sector are studied. …

Gluing constructions for Higgs bundles over a complex connected sum
… space of $\text{Sp(4}\text{,}\mathbb{R}\text{)}$-Higgs bundles, or equivalently the $\text{Sp(4}\text{,}\mathbb{R}\text{)}$-character variety, are partially labeled by an integer $d$ known as the Toledo invariant. The subspace for which this integer attains a maximum has been shown to have $3\cdot …
