Initial Conditions for Cosmic Inflation, the History of the Dark Sector, and Dark-Onium
… for large-field models. The particle nature of dark matter is still a mystery. This thesis very briefly summarizes what we know about dark matter and our current efforts to detect it. This thesis also provides the basic tools necessary to calculate the thermal history of the dark sector. Then …

Search for emerging-jet signatures in pp collisions at 13 TeV with CMS using a fully data-based method for background extraction
… of 13 TeV. 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 …

The Rise of the Dark Side: Dark Pool Trading and the Two-Tiered Implication
… and public trading venues, creating a framework dark and light trading liquidity. Private or non-publicly visible liquidity is housed in dark venues while liquidity visible to the public sits in light locations. Light markets follow strict real-time public reporting requirements for trade volume …

Exploring Non-Minimality in New Physics Beyond the Standard Model
… then focuses on new physics relating to the dark sector. We begin by developing an entirely general analysis framework with which to structure searches for scalar operator `fifth forces' that may arise between Standard Model particles due to the exchange of new light states. By encapsulating …

Forces and gauge groups beyond the standard model
… and gauge groups. I investigate a model where dark matter interacts through a new massive U(1) gauge boson which kinetically mixes with the photon, and show how this model can be tested at neutrino experiments. Supersymmetry may explain the smallness of the Higgs mass compared to the Planck …

Computational Atomic Structure and Search for New Physics
… second half of the dissertation, we consider \dark force" extensions tothe the SM. We introduce \dark forces" by considering the parity-odd as well assimultaneous parity-and time-reversal-violating interactions between atomic electronsand nucleons. Here we hypothesize the exchange of a \dark …

Exploring dark matter locally via a hierarchy of stellar systems
… electromagnetic radiation. The nature of this dark matter remains an unsolved mystery. In this thesis we attempt to discover what constraints can be placed on dark matter from an analysis of a variety of stellar systems in the Local Group. The simplest composite stellar system is a stellar …
