Description

CUPID-Mo is a demonstrator located in Modane, France for the proposed upgrade of the ton-scale 0νββ search experiment CUORE. CUPID-Mo searches for 0νββ decay in $^{100}$Mo via an array of 20 enriched Li$_2$MoO$_4$ (LMO) crystals (0.2 kg) with Ge-wafer light detectors to discriminate between α and β/γ events via collection of both heat and scintillation light. Lower thresholds can allow for low energy dark matter searchers. This can be accomplished by an Optimum Trigger (OT) which constructs a matched filter using the expected signal increasing the SNR and significantly improves triggering compared to a standard derivative trigger. With thresholds improved to <10 keV and further improvements possible, searching for spin-dependent dark matter interactions with Li in LMO crystals becomes promising. Here we present the improvements in energy threshold from the OT and prospects for a low energy dark matter search.
