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…
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…
An assay-based background projection for the MAJORANA DEMONSTRATOR using Monte Carlo Uncertainty Propagation
I. J. Arnquist, F. T. Avignone, A. S. Barabash +53
The background index is an important quantity which is used in projecting and calculating the half-life sensitivity of neutrinoless double-beta decay () experiments. A nov…
Exotic dark matter search with the Majorana Demonstrator
I. J. Arnquist, F. T. Avignone, A. S. Barabash +56
With excellent energy resolution and ultra-low level radiogenic backgrounds, the high-purity germanium detectors in the Majorana Demonstrator enable searches for several classes of…
