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 of the Tritium Absorption InfraRed Spectroscopy (T2ApIR) experiment
Alexander Marsteller, Dominic Batzler, Beate Bornschein +10
The literature on experimentally verified material properties of tritium is sparse but information about this is crucial in fusion for pellet production (Magnetic Confined Fusion),…
Commissioning of an experiment for thermodynamic and spectroscopic studies of hydrogen isotopologues at cryogenic conditions
Joshua KohpeiÃ, Dominic Batzler, Beate Bornschein +7
To study thermodynamic properties and dynamic phase space behavior of hydrogen isotopologues (Q) at cryogenic temperatures and at high density, the Tritium Absorption InfraRed…
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…
First constraints on general neutrino interactions based on KATRIN data
M. Aker, D. Batzler, A. Beglarian +130
The precision measurement of the tritium -decay spectrum performed by the KATRIN experiment provides a unique way to search for general neutrino interactions (GNI). All theoret…
