This White Paper, prepared for the Fundamental Symmetries, Neutrons, and Neutrinos Town Meeting related to the 2023 Nuclear Physics Long Range Plan, makes the case for double beta…
Modeling Backgrounds for the MAJORANA DEMONSTRATOR
C. R. Haufe, I. J. Arnquist, F. T. Avignone +55
The MAJORANA DEMONSTRATOR is a neutrinoless double-beta decay () experiment containing 30 kg of p-type point contact germanium detectors enriched to 88% in 76Ge and $\s…
Charge Trapping and Energy Performance of the MAJORANA DEMONSTRATOR
I. J. Arnquist, F. T. Avignone, A. S. Barabash +55
P-type point contact (PPC) high-purity germanium detectors are an important technology in astroparticle and nuclear physics due to their superb energy resolution, low noise, and pu…
Search for keV-scale Sterile Neutrinos with first KATRIN Data
M. Aker, D. Batzler, A. Beglarian +128
In this work we present a keV-scale sterile-neutrino search with the first tritium data of the KATRIN experiment, acquired in the commissioning run in 2018. KATRIN performs a spect…
Search for Lorentz-Invariance Violation with the first KATRIN data
M. Aker, D. Batzler, A. Beglarian +130
Some extensions of the Standard Model of Particle Physics allow for Lorentz invariance and Charge-Parity-Time (CPT)-invariance violations. In the neutrino sector strong constraints…
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…
Final Result of the MAJORANA DEMONSTRATOR's Search for Neutrinoless Double- Decay in Ge
I. J. Arnquist, F. T. Avignone, A. S. Barabash +57
The MAJORANA DEMONSTRATOR searched for neutrinoless double- decay () of Ge using modular arrays of high-purity Ge detectors operated in vacuum cryostats in a low-ba…
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…
Search for solar axions via axion-photon coupling with the Majorana Demonstrator
I. J. Arnquist, F. T. Avignone, A. S. Barabash +55
Axions were originally proposed to explain the strong-CP problem in QCD. Through the axion-photon coupling, the Sun could be a major source of axions, which could be measured in so…
Experimental study of 13C(α,n)16O reactions in the Majorana Demonstrator calibration data
MAJORANA Collaboration, I. J. Arnquist, F. T. Avignone +55
Neutron captures and delayed decays of reaction products are common sources of backgrounds in ultra-rare event searches. In this work, we studied C(O reactions in…
KATRIN: Status and Prospects for the Neutrino Mass and Beyond
M. Aker, M. Balzer, D. Batzler +159
The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure a high-precision integral spectrum of the endpoint region of T2 beta decay, with the primary goal of probi…
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…
