Darkness Beyond Unitarity
Pouya Asadi, MIT
Event Type: HEP Seminar
Time: 2:00 PM - 3:00 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: There has been substantial effort on searching for thermal Dark Matter DM in the conventional mass window of GeV to tens of TeV without any positive results. This null result has motivated efforts to develop new dynamics in the dark sector that allow us go beyond the usual thermal DM mass window. In this talk, I introduce two such simple dynamics. First I will point out a potentially dramatic effect on the DM abundance in a class of confining dark sectors during its deconfinement phase transition. I will then switch to an even simpler setup where entropy dump into SM from decay of another thermal relic can open up a substantial parameter space for DM mass. I will discuss the viable mass range for DM in each setup and how it is affected by details of dark sector dynamics. I will also discuss ways we can probe such setups in future.
