Description

Liquid xenon-based dark matter experiments can gain substantial sensitivities to light dark matter interactions from the Migdal effect, which predicts that a nuclear recoil (NR) can be accompanied by detectable atomic ionization or excitation signals. This talk draws on our theoretical and experimental studies of NR Migdal interactions to discuss their predicted characteristics and observable signatures in liquid xenon detectors. I will discuss the challenges of directly observing Migdal signals using neutron-induced xenon recoils and present possible measurement strategies to achieve a much-needed confirmation.
