Add to Calendar 3/16/2018 12:00 pm 3/16/2018 1:00 pm America/Chicago High Energy Phenomenology Seminar: Concentrated Dark Matter DESCRIPTION:

I will discuss a new mechanism for the primordial creation of dark matter, “co-decay”, where hidden sector particles comprising the dark matter have little or no interaction with the Standard Model.  So how does one detect it? The hidden sector leads to a matter-dominated phase before Big Bang Nucleosynthesis, which results in enhanced growth of dark matter on small scales and the production of primordial black holes.  If the enhanced sub-structure survives until today it implies interesting implications for indirect detection experiments.  Whereas a more provocative result is that the mass of the most populated black holes resulting from this epoch is within the mass range recently detected by LIGO. I will also discuss how the hypothesis that part of the dark matter is primordial black holes can be tested.
