Strongly-Coupled Dark Sectors: From Cosmology to Colliders

New strongly-coupled confining dark sectors have found application throughout numerous areas of particle physics, extending from dark matter itself, to theories that address the hierarchy problem, to providing a vast array of new collider signals. I'll provide an overview of the theory space, the dark matter candidates, and then discuss some very simple theories that have surprising dark matter and collider physics properties. The elastic scattering cross section for direct detection experiments can be highly suppressed for dark baryons due to the structure of theory and the symmetries that survive confinement. Dark mesons can be strongly constrained by disappearing track searches as well as resonant production and decay, the latter arising because of a global-gauge-gauge anomaly that was not previously recognized. I'll conclude with a brief discussion of other fascinating results and mention some of the many open questions that remain.
