Title:
Abstract:
Over the past two decades, the reach of dark matter direct detection (DMDD) experiments has steadily advanced, driven by substantial improvements in both detector size and performance and background mitigation. As DMDD experiment continue to grow in scale, however, they will soon become sensitive to a new source of background: the coherent elastic scattering of solar neutrinos with atomic nuclei. This neutrino background is impossible to avoid or reduce without major modifications to the design of our detectors, and will ultimately lead to a so-called neutrino floor, below which further exploration of the DM parameter space will become prohibitively expensive. However, this future challenge for DMDD experiments also presents us with an opportunity to study neutrino physics at an energy scale far below that probed at most dedicated neutrino experiments. In this talk, I will discuss the topics that have been the focus of my research over the past three years: can future DMDD experiments be used to constrain models of new, light physics in the neutrino sector; could these constraints be competitive with those obtained from large, dedicated neutrino detectors; and could they be used to test solutions to ongoing mysteries in particle physics, including the muon g-2 anomaly?
