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. …

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 …

Phenomenology of the minimal <i>B - L</i> Model: the Higgs sector at the Large Hadron Collider and future linear colliders
… devoted to the study of the phenomenology of the Higgs sector of the minimal <i>B - L</i> extension of the Standard Model at present and future colliders. Firstly, the motivations that call for the minimal <i>B - L</i> extension are summarised. In addition, the model is analysed in its salient …

Phenomenology of new physics beyond the Standard Model: signals of Supersymmetry with displaced vertices and an extended Higgs sector at colliders
… colliders in testing a model with an extended Higgs sector with a scalar triplet, doublet and singlet; the discovery potential at the Large Hadron Collider (LHC) of a non-minimal Supersymmetric model via conventional sparticle searches and via searches for displaced vertices; and the …

The Use of Operator Regularization in the Computation of Effective Field Theories
… theory as well as up to one loop order for the Higgs sector of the Minimal Supersymmetric Model. Additionally, the renormalization group functions for the <strong>θ</strong>{4}{4} model are calculated from the finite parts of the Greens functions.</p>

Linear Sigma Models in QCD and S3 Symmetry for Neutrinos
… well as for (at a different scale) an effective Higgs sector for some recently proposed walking technicolor models. The model is applied to the s-wave pion-pion scattering in QCD. Both the near threshold region and (with an assumed unitarization) the "global" region up to about 800 MeV are …

Electroweak physics and evidence for a Higgs boson decaying to a pair of tau leptons with the CMS detector
… model of particles. Evidence of the 125 GeV Higgs boson decay to a pair of tau leptons with an observed significance of 3.1 standard deviations is established. The nature of the Higgs sector is probed through searches for neutral resonances decaying to a pair of tau leptons in gluon-fusion …

Electroweak symmetry breaking in the era of the Higgs boson discovery
… lore, we show that a visible dynamics in the Higgs sector can contribute to supersymmetry breaking, as long as soft masses receive contributions also from one or more hidden sectors. A striking feature is the presence of a light pseudo-goldstino in the spectrum. We study potential collider …

Constraints on New Physics from Various Neutrino Experiments
… R-parity violating SUSY, and extended Higgs sector models. In several cases, we find that the limits thus obtained could be competitive with those expected from direct searches at the LHC. In the event that any of the particles discussed here are discovered at the LHC, then the …

Higgs production via weak boson fusion in the Standard Model and the MSSM
Higgs production via weak boson fusion (WBF) is an interesting and important process at both the LHC and a future linear collider. Not only is it a possible Higgs discovery channel, but it also allows us to study the properties of the Higgs boson and the mechanism of electroweak symmetry breaking. …

Topological effects in particle physics phenomenology
… topological terms, we then apply it to Composite Higgs models based on a variety of coset spaces $G/H$ and discuss their phenomenology. For example, we point out the existence of an AB term in the minimal Composite Higgs model based on $SO(5)/SO(4)$, whose phenomenological effects arise only at …
