Theory Division

A gathering of the theorists from KEK and Fermilab, at Fermilab; September 26–30. The schedule is deliberately kept light to allow lots of discussion time. All talks will take place in Wilson Hall 3NW (near the coffee machine on the theory floor), and are 45 minutes each, unless otherwise stated. Peruse the program.

We present a novel dark matter (DM) candidate, Elastically Decoupling Relic (ELDER), in which the DM current-day abundance is dominantly determined via the elastic decoupling between standard model particles and DM, rather than a usual DM freeze-out. ELDER has a distinctive thermal history and new phenomenological implications in comparison to the CDM/WIMP scenarios. It provides... More »

Direct detection experiments for dark matter are increasingly ruling out large parameter space. However, light dark matter models with particle masses < GeV are still largely unconstrained. In this talk, I will present the examination of a proposal to use atom interferometers to detect a light dark matter subcomponent at sub-GeV masses. Dark matter scattering off one “arm” of... More »
