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…

An active Transverse Energy Filter based on microstructured Si-PIN diodes with an angular-selective detection efficiency

S. Schneidewind, K. Gauda, K. Blümer +10

Si-PIN detectors can be microstructured to achieve angular-selective particle detection capabilities, which we call active Transverse Energy Filter (aTEF). The microstructuring con…

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…

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…

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…
