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…

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 K…

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 theoreti…

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…

Direct neutrino-mass measurement based on 259 days of KATRIN data

M. Aker, D. Batzler, A. Beglarian +146

The fact that neutrinos carry a non-vanishing rest mass is evidence of physics beyond the Standard Model of elementary particles. Their absolute mass bears important relevance from…

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…
