"Phases of Particle Dark Matter"

Josh Ruderman , NYU
[Host: Jan Heisig]

Dark matter is believed to make up most of the matter in our Universe, but its particle origin remains a mystery.  A favorite candidate is the so-called Weakly Interacting Massive Particle (WIMP), but a diverse set of experiments are rapidly closing the available parameter space for WIMPs.  I will show that small changes to the assumptions about how dark matter was produced in the early Universe lead to very different dark matter masses and interaction strengths.  I will chart ``phase diagrams” for the production of dark matter with a thermal or non-thermal origin.  I will explain how different phases of dark matter production map onto different experimental prospects.
