The Hidden Structures of Composite Dark Matter

Abstract:
While the astrophysical evidence for dark matter is overwhelming, we know very little about the detailed physics of the dark matter sector, and a wide range of dark matter models remain viable. In this talk, I will discuss an intriguing class of models known as composite dark matter, in which the dark matter is a strongly-coupled bound state of more fundamental dark particles. Strongly-coupled hidden sectors can have distinctive signatures in direct detection experiments, dark matter self-interactions, and gravitational wave searches. They can also give rise to more exotic structures, from ultra-heavy nucleus-like bound states to dark stars.
