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 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…

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…

New Constraint on the Local Relic Neutrino Background Overdensity with the First KATRIN Data Runs

M. Aker, D. Batzler, A. Beglarian +129

We report on the direct cosmic relic neutrino background search from the first two science runs of the KATRIN experiment in 2019. Beta-decay electrons from a high-purity molecular…

Improved eV-scale Sterile-Neutrino Constraints from the Second KATRIN Measurement Campaign

M. Aker, D. Batzler, A. Beglarian +128

We present the results of the light sterile neutrino search from the second KATRIN measurement campaign in 2019. Approaching nominal activity, tritium -electr…

First direct neutrino-mass measurement with sub-eV sensitivity

M. Aker, A. Beglarian, J. Behrens +125

We report the results of the second measurement campaign of the Karlsruhe Tritium Neutrino (KATRIN) experiment. KATRIN probes the effective electron anti-neutrino mass, , via…
