Description

The lack of experimental signals of WIMP dark matter to date has brought hidden sector dark matter models into sharp focus: a broad and general class of theories where the relic abundance of dark matter is determined through its interactions with other dark fields, rather than directly with the Standard Model. I'll point out that the existence of an internally thermalized hidden sector places new requirements on early universe cosmology, and talk about physical consequences from two possible scenarios for the origin of a dark sector.
