Study of the sensitivity of CMS to the lepton flavour violating neutrinoless tau decay tau mymymy
… an excellent potential for the search of neutrinoless and therefore lepton flavour violating tau decays. It is already known since the experimental discovery of neutrino oscillations, that the conservation law of the lepton family number is not strict. The neutrino oscillations have …

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
… 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 2[nu][beta][beta] half-lives are found to be T 1/2(¹¹⁶Cd) = (2.90 ± 0.03(stat) ± 0.15(syst)×10¹⁹ yr and T 1/2(⁸²Se) = …

The search for majoron emission in xenon-136 and two-neutrino double-beta decay of xenon-134 with the Enriched Xenon Observatory
… distinguishability 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 …

Double-Beta Decay of 96Zr and Double-Electron Capture of 156Dy to Excited Final States
… Measurements of this decay are important to test neutrinoless double-beta decay nuclear matrix element calculations, which are necessary to extract the neutrino mass from a measurement of the neutrinoless double-beta decay half-life. </p><p>The second experiment is a search for the …

High Purity Germanium detectors for the search of rare events : background discrimination and future prospects with the GENIUS project
… on the search for WIMP dark matter and neutrinoless double beta decay using High Purity Germanium detectors. In modern physics two of the main goals are to find out about the nature of dark matter and to answer the question on the neutrino mass. The HdMoi presently provides the best …

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
… 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. It would also have huge implications for not only particle …

Observation of Singly Charged Barium Ions in a Buffer Gas: Towards a Functional Barium-Tagging System for Use in the Enriched Xenon Observatory
The observation of the rare neutrinoless-double-beta-decay will have major implications for both neutrino physics and particle physics on a whole. A positive observation will confirm the Majorana nature of the neutrino and demonstrate that lepton number is not strictly conserved. Furthermore, a …

Deep Learning for the KamLAND-Zen Search for 0𝜈𝛽𝛽
Neutrinoless double beta decay (0𝜈𝛽𝛽) is a major interest in neutrino physics. Discovery of 0𝜈𝛽𝛽 would demonstrate that neutrinos are Majorana fermions and that lepton number is not a symmetry of nature, thus providing a possible explanation for the observed matter-antimatter asymmetry of the …
