Dark matter Phenomenology with Vector Portals

This thesis will consider theoretical constructions for dark matter candidates interacting with standard model particles via the exchange of a spin-one mediator. The UV origin of such a mediator is a new Abelian gauge symmetry that is spontaneously broken to provide mass to the vector portal field. We will focus on self-consistent quantum field theoretical constructions and we will investigate phenomenological constraints from direct and direct searches as well as colliders.
