Rare Multinucleon Decays with the Full Data Sets of the Majorana Demonstrator / I.J.Arnquist, F.T.Avignone III, S.Vasilyev, [a.o.]. – Text : electronic // Physical Review C. – 2025. – Vol. 112, No. 2. – P. L022501. – URL: https://doi.org/10.1103/2pgp-hvst.
The Majorana Demonstrator was an ultra-low-background experiment designed for neutrinoless double-beta decay (0𝜈𝛽𝛽) investigation in *7*6Ge. Located at the Sanford Underground Research Facility in Lead, South Dakota, the Demonstrator utilized modular high-purity Ge detector arrays within shielded vacuum cryostats, operating deep underground. The arrays, with a capacity of up to 40.4 kg (27.2 kg enriched to ∼88% in *7*6Ge), have accumulated the full data set, totaling 64.5 kg yr of enriched active exposure and 27.4 kg yr of exposure for natural detectors. Our updated search improves previously explored three-nucleon decay modes in Ge isotopes, setting new partial lifetime limits of 1.83 × 10*2*6 yr (90% confidence level) for *7*6Ge(𝑝𝑝𝑝) → *7*3Cu 𝑒*+𝜋*+𝜋*+ and *7*6Ge(𝑝𝑝𝑛) → *7*3Zn 𝑒*+𝜋*+. The partial lifetime limit for the fully inclusive triproton decay mode of *7*6Ge is found to be 2.1 × 10*2*5 yr. Furthermore, we have updated limits for corresponding multinucleon decays.
