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…
Conversion electrons used to monitor the energy scale of electron spectrometer near tritium endpoint - a simulation study
M. Rysavy
Measurements of the endpoint region of the tritium beta-decay spectrum provides good possibility to determine neutrino mass. This, however, needs a perfect monitoring of the spectr…
On the reliability of the theoretical internal conversion coefficients
M. Rysavy, O. Dragoun
Possible sources of uncertainties in the calculations of the internal conversion coefficients are studied. The uncertainties induced by them are estimated.
