First Results on the Search for Lepton Number Violating Neutrinoless Double Beta Decay with the LEGEND-200 Experiment
H. Acharya, N. Ackermann, M. Agostini +256
The LEGEND collaboration is searching for neutrinoless double beta () decay by operating high-purity germanium detectors enriched in Ge in a low-background liquid a…
Rare multi-nucleon decays with the full data sets of the Majorana Demonstrator
I. J. Arnquist, F. T. Avignone, A. S. Barabash +39
The Majorana Demonstrator was an ultra-low-background experiment designed for neutrinoless double-beta decay () investigation in Ge. Located at the Sanford Undergro…
Final Results of the MAJORANA DEMONSTRATOR's Search for Double-Beta Decay of Ge to Excited States of Se
I. J. Arnquist, F. T. Avignone, A. S. Barabash +45
Ge can decay into three possible excited states of Se, with the emission of two or, if the neutrino is Majorana, zero neutrinos. None of these six transitions…
Machine learning-powered data cleaning for LEGEND: a semi-supervised approach using affinity propagation and support vector machines
E. León, A. Li, M. A. Bahena Schott +8
Neutrinoless double-beta decay () is a rare nuclear process that, if observed, will provide insight into the nature of neutrinos and help explain the matter-antimatter asy…
Search for charge nonconservation and Pauli exclusion principle violation with the Majorana Demonstrator
MAJORANA Collaboration, I. J. Arnquist, F. T. Avignone +55
Charge conservation and the Pauli exclusion principle result from fundamental symmetries in the standard model of particle physics, and are typically taken as axiomatic. High-preci…
The MAJORANA DEMONSTRATOR experiment's construction, commissioning, and performance
N. Abgrall, E. Aguayo, I. J. Arnquist +108
Background: The MAJORANA DEMONSTRATOR , a modular array of isotopically enriched high-purity germanium (HPGe) detectors, was constructed to demonstrate backgrounds low enough to ju…
