Current Status and Results from CUPID-Mo in the search for Neutrinoless Double Beta Decay

CUPID-Mo is a demonstrator experiment for CUPID (CUORE Upgrade with Particle ID), the planned next-generation upgrade of the first ton scale cryogenic bolometric $0\nu\beta\beta$ decay experiment, CUORE (Cryogenic Underground Observatory for Rare Events). CUPID-Mo was operated at Laboratoire Souterrain de Modane in France as an array of 20 enriched Li$_{2}$$^{100}$MoO$_{4}$ (LMO) cylindrical crystals ($\sim$200g each) each featuring a Ge light detector (LD) all at $\sim$20 mK. The LMOs and LDs were instrumented with NTD sensors allowing for the collection of both heat and scintillation light. This dual mode of energy collection allows for $\alpha$ events to be distinguished from $\beta$/$\gamma$ events, significantly reducing the background from degraded $\alpha$s in the heat channel. CUPID-Mo has a demonstrated bolometric energy resolution of $\sim$7 keV (FWHM) at 2615 keV, complete $\alpha$ / $\beta$/$\gamma$ discrimination and very low radioactive contamination. Here we report an overview of the current leading results in the search for $0\nu\beta\beta$ with CUPID-Mo using $\sim$2 kg-years of exposure, an analysis using a $^{56}$Co source to characterize the energy resolution scaling, and an overview of other ongoing CUPID-Mo analyses.
