Double-Beta Decay of 96Zr and Double-Electron Capture of 156Dy to Excited Final States
… searches for second-order weak nuclear decays to excited final states were conducted. Both experiments were carried out at the Kimballton Underground Research Facility to provide shielding from cosmic rays. The first search is for the two-neutrino double-beta decay of 96Zr to excited …

Search for neutrinoless double-beta decay and 42Ar in enriched xenon using the EXO-200 dataset
Observation of neutrinoless double-beta decay (0νββ) would constitute discovery of a new class of particle (the Majorana neutrino), violate lepton number conservation, and provide a constraint on the neutrino mass scale. The Enriched Xenon Observatory experiment (EXO-200) operated an extremely …

Search for neutrinoless double beta decay of ¹¹⁶Cd and ⁸²Se and calorimeter simulations for the SuperNEMO experiment
… used to measure the half-life of two-neutrino double beta decay (2[nu][beta][beta]) to the ground states of ¹¹⁶Sn and ⁸²Kr and to place a lower limit on the neutrinoless double becay decay (0[nu][beta][beta]) to the same ground states. Under the single-states dominance hypothesis, the …

The search for majoron emission in xenon-136 and two-neutrino double-beta decay of xenon-134 with the Enriched Xenon Observatory
… is by searching for neutrinoless double-beta decay, a very rare theorized process not allowed under the current theoretical framework of particle physics. Positive observation of neutrinoless double-beta decay would usher in a revolution in particle physics, since it would …

Experimental and theoretical multi-channel study of direct nuclear reactions: a tool to provide data driven information on neutrino-less double-beta decay
The search for neutrino-less double beta (0vbb) decay has attracted much interest in the last years due to the extraordinary consequences that could derive from its observation. The NUMEN project aims to provide experimental information on the nuclear matrix elements involved in the expression of …

Attenuation of the scintillation light in liquid argon and investigation of the double beta decay of ⁷⁶Ge into excited states of ⁷⁶Se in the GERDA experiment
… GERDA experiment searches for the neutrinoless double beta (0𝜈𝛽𝛽) decay of Ge-76. The observation of this decay would prove the Majorana character of the neutrino, i.e. that it is its own antiparticle. This would clarify the question which neutrino mass ordering is realized in nature and give a …

Radioactive source measurements in a liquid xenon time projection chamber
Double beta decay is a rare nuclear process that can occur in two different modes. The first is known as the two-neutrino double beta decay, which is a second-order weak interaction process and has already been observed in several nuclei. The second one is called neutrino less double beta decay. …

Measurement of the double beta decay half-life of ^{100}Mo to the 0^{+}_{1} excited state, and ^{48}Ca to the ground state in the NEMO 3 experiment
NEMO 3 is a double beta decay experiment situated in the Fréjus tunnel which runs between France and Italy. If neutrinoless double beta decay is observed it will prove the neutrino is a Majorana particle and may potentially become the most sensitive method of measuring the absolute neutrino mass. …
