The WIMP Next Door: Simplified Models for Hidden Sector Dark Matter

As the hunt for the elusive dark matter progresses, an impressive series of null results has severely limited options for DM that freezes out via standard model interactions. A hidden sector containing the dark matter particle and an unstable mediator can freezeout independently of the sector's very weak connection to the standard model fields, opening opportunities for phenomenology. I will present two minimal simplified models for hidden sector freezeout (through the vector and scalar portal), discuss the existing constraints on these parameter spaces from a wide array of complementary experimental approaches, and address how the features of these models survive in extensions beyond the minimal case.
