KATRIN Sensitivity to keV Sterile Neutrinos with the TRISTAN Detector Upgrade
H. Acharya, M. Aker, D. Batzler +127
Sterile neutrinos in the keV mass range are a well-motivated extension of the Standard Model and viable dark matter candidates. Their existence can be probed in laboratory experime…
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…
Sterile-neutrino search based on 259 days of KATRIN data
Himal Acharya, Max Aker, Dominic Batzler +132
Neutrinos are the most abundant fundamental matter particles in the Universe and play a crucial role in particle physics and cosmology. Neutrino oscillation, discovered about 25 ye…
Measurement of the inhomogeneity of the KATRIN tritium source electric potential by high-resolution spectroscopy of conversion electrons from Kr
H. Acharya, M. Aker, D. Batzler +130
Precision spectroscopy of the electron spectrum of the tritium -decay near the kinematic endpoint is a direct method to determine the effective electron antineutrino mass. The…
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…
