  2. Disclaimer You’re probably tired…it’s Day 4, after Lunch… My promises to you: • This slide has by far the most text (besides the summary). • I’ll start my talk with story time! • There’s not a single equation! • I’ve hidden a picture of Einstein! Robert McGehee

  30. Summary Relaxing DM stability assumptions allows for novel signals and operators. Neutral current operators yield peaked, correlated nuclear recoil (NR) signals. Charged current operators yield β − , NR, and γ signals. New searches at existing experiments can probe both neutral and charged current operators. Fermionic DM absorption is an exciting playground for both experiments and model building! Robert McGehee
