dc.description.abstract	We report on the measurement of the two-neutrino double-β decay of 82Se performed for the first time with cryogenic calorimeters, inthe framework of theCUPID-0experiment. With anexposureof 9.95 kg yr of Zn82Se, we determine the two-neutrino double-β decay half-life of 82Se with an unprecedentedprecision level, T2ν½ = [8.60 0.03(stat)þ0.19 −0.13(syst)]× 1019 yr. The very high signal-to-background ratio, along with the detailed reconstruction of the background sources allowed us to identify the single state dominance as the underlying mechanism of such a process, demonstrating that the higher state dominance hypothesis is disfavored at the level of 5.5σ.	en
