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…

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…

Measurement of the electric potential and the magnetic field in the shifted analysing plane of the KATRIN experiment

M. Aker, D. Batzler, A. Beglarian +135

The projected sensitivity of the effective electron neutrino-mass measurement with the KATRIN experiment is below 0.3 eV (90 % CL) after five years of data acquisition. The sensiti…

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…
