Leave No Stone Unturned Requiem for a WIMP Robert McGehee

Leave No Stone Unturned Requiem for a WIMP 1. Theory: everyone’s alternatives ( future ) 2. Experiment: larger or lighter ( future ) Robert McGehee

Leave No Stone Unturned Requiem for a WIMP 1. Theory: everyone’s alternatives ( future ) 2. Experiment: larger or lighter ( future ) 3. Both: new DM & signals ( present ) i. DM scattering off electrons (Essig, Mardon, Volansky [1108.5383]) ii. Boosted DM (Agashe, Cui, Necib, Thaler [1405.7370]) iii. Self-Destructing DM (Grossman, Harnik, Telem, Zhang [1712.00455]) iv.

LiH proposal by Budnik et al [1705.03016] Robert McGehee

Summary Relaxing DM stability assumptions allows for novel signals and operators. Charged current operators induce β ± decays with NR, 𝑓 ± , and γ signals. Neutral current operators yield peaked, correlated nuclear recoil (NR) signals. New searches at existing experiments can probe both neutral and charged current operators. Stay tuned for absorption by electrons! Robert McGehee
