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…
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…
An active transverse energy filter to differentiate low energy particles with large pitch angles in a strong magnetic field
K. Gauda, S. Schneidewind, G. Drexlin +11
We present the idea and proof of principle measurements for an angular-selective active filter for charged particles. The motivation for the setup arises from the need to distingui…
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…
Precision measurement of the electron energy-loss function in tritium and deuterium gas for the KATRIN experiment
M. Aker, A. Beglarian, J. Behrens +132
The KATRIN experiment is designed for a direct and model-independent determination of the effective electron anti-neutrino mass via a high-precision measurement of the tritium -…
The Design, Construction, and Commissioning of the KATRIN Experiment
M. Aker, K. Altenmüller, J. F. Amsbaugh +226
The KArlsruhe TRItium Neutrino (KATRIN) experiment, which aims to make a direct and model-independent determination of the absolute neutrino mass scale, is a complex experiment wit…
Analysis methods for the first KATRIN neutrino-mass measurement
M. Aker, K. Altenmüller, A. Beglarian +126
We report on the data set, data handling, and detailed analysis techniques of the first neutrino-mass measurement by the Karlsruhe Tritium Neutrino (KATRIN) experiment, which probe…
Bound on 3+1 active-sterile neutrino mixing from the first four-week science run of KATRIN
M. Aker, K. Altenmueller, A. Beglarian +126
We report on the light sterile neutrino search from the first four-week science run of the KATRIN experiment in~2019. Beta-decay electrons from a high-purity gaseous molecular trit…
