Interpretable Boosted Decision Tree Analysis for the Majorana Demonstrator
I. J. Arnquist, F. T. Avignone, A. S. Barabash +52
The Majorana Demonstrator is a leading experiment searching for neutrinoless double-beta decay with high purity germanium detectors (HPGe). Machine learning provides a new way to m…
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…
Examining LEGEND-1000 cosmogenic neutron backgrounds in Geant4 and MCNP
C. J. Barton, W. Xu, S. R. Elliott +1
For next-generation neutrinoless double beta decay experiments, extremely low backgrounds are necessary. An understanding of in-situ cosmogenic backgrounds is critical to the desig…
