Viscosity measurements of gaseous H2 between 200 K to 300 K with a spinning rotor gauge

Johanna Wydra, Robin Größle, Alexander Marsteller +4

Experimental values for the viscosity of the radioactive hydrogen isotopologue tritium are still unknown in literature. Existing values from ab initio calculations disregard quantu…

Operation Modes of the KATRIN Experiment Tritium Loop System using Kr

Alexander Marsteller, Beate Bornschein, Matthias Böttcher +12

The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to search for the effective electron antineutrino mass with a sensitivity of 0.2 eV (90 % C.L.). In order to achieve this go…

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…
