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…

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…

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 -…

First operation of the KATRIN experiment with tritium

M. Aker, K. Altenmüller, M. Arenz +168

The determination of the neutrino mass is one of the major challenges in astroparticle physics today. Direct neutrino mass experiments, based solely on the kinematics of beta-decay…
