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 …

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 …

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. …

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 …

Sensitivity Models for [Beta]+/EC Discovery in Large-Volume Scintillation Detectors
In this thesis, we consider the [Beta]+/EC decay of 124Xe and take the first steps towards characterizing a hypothetical experiment to detect it, making use of techniques traditionally employed in neutrinoless double beta decay experiments. We use a simulated large-volume scintillation detector …

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 …
