Searching for Beyond the Standard Model physics using the improved description of ${}^{100}$Mo $2\nu \beta \beta$ decay spectral shape with CUPID-Mo

C. Augier, A. S. Barabash, F. Bellini +80

The current experiments searching for neutrinoless double-$\beta$ ($0\nu \beta \beta$) decay also collect large statistics of Standard Model allowed two-neutrino double-$\beta$ ($2\nu \beta \beta$) decay events.…
