註釋The unexplained presence of a large component of invisible matter in our universe is a compelling mystery. This Dark Matter (DM) is needed to solve a number of puzzles on astrophysical and cosmological scales, and should be something exotic, something beyond the matter that we currently know about. A compelling answer to the DM puzzle is the idea that DM is a Weakly Interacting Massive Particle (WIMP), which is where the DM is an exotic particle that obtains its currently observed abundance by falling out of thermal equilibrium with the primordial plasma in the early universe. If the strength of the interaction is around the electroweak scale, then just the right abundance of DM is obtained. This gives a good motivation to search for GeV-TeV scale exotic particles that might make up all or part of the DM. The Large Hadron Collider (LHC) is a machine purpose built to find new particles in this energy range. Therefore, it is inevitable to want to search for DM at the LHC, and a large number of competing theories are on the market which allow us to do so. In this thesis we will be studying consistent models for DM at the LHC. As we will explain, starting from model-independent Effective Field Theories (EFTs) of DM interactions, a framework of simplified models has been built up. We will explore the constraints LHC data impose on these simplified models, propose more consistent theories, examine the parameter space of these UV-completions, and propose a new LHC search based on an extended version of a simplified model.
