Massive stable charged particle signatures in simulations at the LHC
… of the standard model attempt to solve current problems in the standard model such as the Hierarchy Problem. The Hierarchy Problem centers on the lack of an explanation in the standard model for the weakness of the force of gravity compared to the other forces of nature. Current research in …

E6 inspired supersymmetric models
… higher energy physics, but do not contain the mu-problem or little hierarchy problem of the Minimal Supersymmetric Standard Model (MSSM). Also, unlike conventional Grand Unified Theories, the E6 inspired models do not contain any doublet-triplet splitting and the Minimal E6 Supersymmetric Model …

Relevant Operators of Particle Physics and Cosmology
… Model is the Higgs mass which causes the "hierarchy problem", while the cosmological constant term of cosmology results in the "cosmological constant problem". In this thesis defense, I will discuss about how these issues can guide us in the pursuit of searching for new physics, both from a …

The Development of the ATLAS SCT as a Luminometer and the Search for SUSY Decays with Compressed Mass Spectra
… matter candidate) as well as the fact that the hierarchy problem violates naturalness arguments. This has motivated the construction of particle accelerators to probe fundamental particles at increasingly high center-of-mass energies and luminosities, the LHC at CERN being the latest to continue …

Loop Transformations for the Optimized Generation of Reconfigurable Hardware
… on parallelism. This thesis addresses the memory hierarchy problem to high-level transformations of loop structures. The composition of long transformation sequences by combining shorter subsequences is studied together with the influence of the order of applying transformation steps. Several …

Signals from portals to non-minimal hidden sectors
… Model (SM) gauge groups can address some of the problems of the SM, such as the origin of neutrino masses, the little hierarchy problem, and the nature of dark matter. In these scenarios, interactions of the HS with the SM are only possible through terms in the Lagrangian that couple gauge …

Above and beyond the standard model : on phenomenology of Lee-Wick theory and massive vector color-octet
… (LW SM), which, by providing a solution to the Hierarchy problem, forms a natural extension of the electroweak sector, while Part II studies the coloron theory, arising from extending the strong sector gauge group.Providing a general introduction about the current state of the SM and the …

Search For Contact Interactions Using The Dimuon Mass Spectrum In P-P Collisions At Sqrt(s) = 8 Tev At Cms
<p>The mass hierarchy problem associated with the standard model suggests that there might be more fundamental particles in nature. If quarks and leptons have substructures, known as preons, the manifestation of compositeness can be a four-fermion contact interaction. The experimental signal for …

Modeling beta decay spectra to analyze the sensitivity of a neutrino mass experiment
… inference can be extended to the neutrino mass hierarchy problem.

Radiative symmetry breaking in the supersymmetric minimal B-L extended standard model
… SM extension which resolves the neutrino mass problem, the dark matter problem, and the hierarchy problem, and which has the ability to explain the observed baryon asymmetry of the Universe. When we include quantum corrections to the Higgs potential of the model, we find that Radiative B-L …

Phenomenological aspects of the E6SSM

Aspects of electroweak symmetry breaking in physics beyond the standard model
… As a supersymmetric theory it solves the SM hierarchy problem and by breaking a new gauged U(1) symmetry it also solves the μ-problem of the MSSM. We investigate the Renormalisation Group Evolution of the model and test for radiative electroweak symmetry breaking in two versions of the model …

Radon Detection and 241Am-7Li Source Development for the Lux-Zeplin Dark Matter Experiment
… which if it exists, could also resolve the gauge hierarchy problem in particle physics. WIMPs are theorized to interact with certain detector materials such as liquid xenon (LXe), via the weak force, active on all other known particles, and produce nuclear recoil (NR). However, this detection …

Searches for supersymmetric particles in events with two opposite-sign same-flavor leptons, jets, and large missing transverse energy
… which are crucial for the SUSY solution to the hierarchy problem. For the searches for the light higgsinos, low transverse momentum Z + jets events are an important background, which will be a major focus of the ATLAS SUSY program in the following years. The photon template method is unavailable …
