SUMMARY:Lecture / Discussion:HET Seminar | The Search for Light Dark Matter
DESCRIPTION:Recent years have seen a dramatic expansion in ideas regarding the nature of dark matter\, extending beyond the WIMP paradigm. Many of these theories predict minuscule couplings between light (sub-GeV mass) dark matter and the Standard Model\, which direct detection experiments can search for. In this talk we will begin by reviewing the status of current electron-based experiments which are achieving extraordinary sensitivity to theoretically well-motivated freeze-in dark matter models. Next\, we discuss how condensed matter sum rules can inform future detector development\, and show how non-relativistic effective field theories can be used to understand the detector response to general dark matter-electron interactions. Finally\, we will discuss how the next generation of direct detection experiments using meV-scale excitations\, such as phonons and magnons\, can begin to probe the sub-MeV dark matter mass frontier.
