Hidden Sector: Three Different Ways
… explore the consequences of different Hidden Sector models in various experimental fields. The first project proposes the Hidden Sector is populated by just one U(1) vector particle. It couples to the Standard Model through kinetic mixing and is responsible for a fraction of Dark Matter …

Cosmology of hidden sector with Higgs portal
… cosmological implications of hidden sector models which involve scalar fields that do not interact with the Standard Model 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 …

Search for emerging-jet signatures in pp collisions at 13 TeV with CMS using a fully data-based method for background extraction
… This search examines a hypothetical dark QCD sector that couples to the standard model through a scalar mediator. The scalar mediator decays into a standard model quark and a dark sector quark. As the dark sector quark showers and hadronizes, it produces long-lived dark mesons that …

Keeping the authority public : public housing preservation and organizational restructuring with the Rental Assistance Demonstration
… PHAs to structurally internalize some private-sector models is a significant development for the organization and management of public housing. Case studies from Cambridge, MA and Tacoma, WA offer evidence of the unique challenges, emergent adaptations, and strategic opportunities for two …

Low-carbon transformation of the German and European electricity systems
… of the German and European electricity sectors. It applies techno-economic electricity sector models to research questions on market design and infrastructure investment. The first part consists of three chapters on Germany. It starts with a chapter on the nodal dispatch model for the …

PHENOMENOLOGY OF THE STANDARD MODEL AND BEYOND
… promising class of BSM theories involves “Hidden Sectors”, which are newparticles and interactions that are singlets under SM gauge symmetries. While minimal hidden sector scenarios have been widely studied, models with non-minimal field content and richer dynamics remain less explored. In the …

New opportunities for equity : a critical examination of community development venture capital
… Venture Capital attempts to link private sector models of capital generation with socially motivated outcomes, namely job creation for low-income workers, while establishing an alternative model to investing in business. This thesis investigates the burgeoning urban CDVC industry through …

Local government : tales of creativity and innovation
… local Councils have often turned to the private sector models of 'entrepreneurialism' and 'innovation' for guidance, but in a number of cases this has not been satisfactory nor overly successful. There has been little work on a model of public sector innovation that integrates the principles of …

Constraints on New Physics from Various Neutrino Experiments
… with the most recent experimental data. The models we consider are: gauged Lmu-Ltau, gauged B-3Lmu, and S1, S3, V1, V3 leptoquarks. We find that only the triplet leptoquark models can explain NuTeV and be compatible with the data from other experiments at the same time, and only if the …

Modal Analysis of General Cyclically Symmetric Systems with Applications to Multi-Stage Structures
… cost for eigensolutions. Finite element models of multi-stage bladed disk assemblies consist of multiple cyclically symmetric bladed disks that are coupled through the boundary nodes at the inter-stage interface. To improve the computational efficiency of calculating the full system …

The welfare cost and greenhouse gas emissions effects of sector-specific energy policies
… standards implemented in different economic sectors and at different levels of government, rather than a more efficient economy-wide carbon tax or cap-and-trade policy. This is evidenced by policies such as state-level Renewable Portfolio Standards (RPSs), national Renewable Fuel Standard …

Supersymmetry Breaking: Models of Gauge Mediation with Gauge Messengers
… It turns out that this does not happen in models where the Kahler potential is canonical, and the superpotential is a cubic polynomial in the fields, but it can happen if either of these constraints is violated. This leads us to consider a particular example, where we study a hidden sector …

Social accounting matrice and computable general equilibrium modelling in South Africa with reference to the financial sector
… (SAMs) and Computable General Equilibrium (CGE) models to give quantitative support in the formulation of income redistribution policies. A SAM can be defined as a numerical representation of the economic cycle with emphasis on income distribution. A CGE model can be defined as an economy-wide …

Essays in Macroeconomics of Emerging Markets
… 1. Law enforcement and the size of the informal sector.</p> <p>I assemble new cross-country evidence showing that contrary to the standard view, the relationship between the size of the informal sector and tax rates is, at best, ambiguous. Law enforcement and informality also show no clear …
