Title: New Physics in the Dark: Precision Cosmology as a probe of Dark Sectors
Abstract: While the presence in the Universe of the ghostly substance known as "dark matter" can be robustly deduced from a plethora of astrophysical and cosmological observations, its nature and origins remain one of the greatest mysteries of modern physics. Moreover, the possibility that dark matter is part of a broader and richer "dark sector" (with its own particles and interactions) is an enticing one, and it is perhaps hinted at by current data. In this talk we motivate complex dark sectors as an exciting and realistic prospect for physics beyond the standard model, and discuss some of the broad, generic features they display, as well as how these features show up in precision cosmology observables. We conclude by showcasing a few interesting examples of dark sectors in the recent literature, and outline future work on this area.
