New Results in the search for $0\nu\beta\beta$ decay in $^{100}$Mo from CUPID-Mo

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), with each LMO featuring a Ge light detector (LD). The LMOs and LDs were operated at $\sim$20 mK and 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. With a demonstrated bolometric energy resolution of $\sim$7 keV (FWHM) at 2615 keV, complete discrimination of $\alpha$'s from $\beta$/$\gamma$'s and very low radioactive contamination, CUPID-Mo is in the background-free regime. Here we present the current leading results of CUPID-Mo with an exposure of over 2 kg-years for the $0\nu\beta\beta$ decay of $^{100}$Mo. In this talk we present the analysis for this result, the current limit and the status of ongoing CUPID-Mo analyses.
