"Final results on Se-82 double beta decay to the ground state of Kr-82 from the NEMO-3 experiment." EUROPEAN PHYSICAL JOURNAL C, Volume 78, Issue 10, pp. ? - ? (15). https://doi.org/10.1140/epjc/s10052-018-6295-x1434-60441434-6052https://hdl.handle.net/2144/37780Using data from the NEMO-3 experiment, we have measured the two-neutrino double beta decay (2𝜈𝛽𝛽) half-life of ^82 Se as 𝑇2𝜈1/2=[9.39±0.17( stat )±0.58( syst )]×10^19 y under the single-state dominance hypothesis for this nuclear transition. The corresponding nuclear matrix element is ∣∣𝑀^2𝜈∣∣=0.0498±0.0016. In addition, a search for neutrinoless double beta decay (0𝜈𝛽𝛽) using 0.93 kg of ^82 Se observed for a total of 5.25 y has been conducted and no evidence for a signal has been found. The resulting half-life limit of 𝑇^0𝜈1/2>2.5×10^23 y (90% C.L. ) for the light neutrino exchange mechanism leads to a constraint on the effective Majorana neutrino mass of ⟨𝑚𝜈⟩<(1.2−3.0) eV , where the range reflects 0𝜈𝛽𝛽 nuclear matrix element values from different calculations. Furthermore, constraints on lepton number violating parameters for other 0𝜈𝛽𝛽 mechanisms, such as right-handed currents, majoron emission and R-parity violating supersymmetry modes have been set.15 p.en-USAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Science & technologyPhysical sciencesPhysics, particles & fieldsPhysicsHalf-lifeValuesQuantum physicsAtomic, molecular, nuclear, particle and plasma physicsNuclear & particles physicsArticle10.1140/epjc/s10052-018-6295-x406295
