Title: Precise measurement of $2νββ$ decay of $$^{100}$$Mo with the CUPID-Mo detection technology

Journal Article · · European Physical Journal. C, Particles and Fields

We report the measurement of the two-neutrino double-beta ($$2\nu\beta\beta$$) decay of $$^{100}$$Mo to the ground state of $$^{100}$$Ru using lithium molybdate (\crystal) scintillating bolometers. The detectors were developed for the CUPID-Mo program and operated at the EDELWEISS-III low background facility in the Modane underground laboratory. From a total exposure of $42.235$ kg$$\times$$d, the half-life of $$^{100}$$Mo is determined to be $$T_{1/2}^{2\nu}=[7.12^{+0.18}_{-0.14}\,\mathrm{(stat.)}\pm0.10\,\mathrm{(syst.)}]\times10^{18}$$ years. This is the most accurate determination of the $$2\nu\beta\beta$$ half-life of $$^{100}$$Mo to date. We also confirm, with the statistical significance of $$>3\sigma$$, that the single-state dominance model of the $$2\nu\beta\beta$$ decay of $$^{100}$$Mo is favored over the high-state dominance model.
