Particle Theory Seminar | Pouya Asadi (MIT) “Dramatic Dynamics in Confining Dark Sectors”

Seminar Organizer

Event Details

The searches for particle Dark Matter (DM) have mostly focused on masses below 100TeV owing to the unitarity bound on thermal DM. In this talk, I will point out some intriguing dynamics in a confining dark sector that opens a vast parameter space beyond the unitarity bound. The key observation is the effect of the first order confinement phase transition in a broad class of confining models that dramatically suppresses the DM abundance. While the effect is independent of the type of portal between SM and the dark sector, I will also study a specific model and further interesting dynamics that it gives rise to in such sectors. This study motivates broadening the scope of current heavy dark matter searches to a new part of the parameter space.
