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…
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…
Measurements with a TRISTAN prototype detector system at the "Troitsk nu-mass" experiment in integral and differential mode
Tim Brunst, Thibaut Houdy, Susanne Mertens +22
Sterile neutrinos emerge in minimal extensions of the Standard Model which can solve a number of open questions in astroparticle physics. For example, sterile neutrinos in the keV-…
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…
An improved upper limit on the neutrino mass from a direct kinematic method by KATRIN
M. Aker, K. Altenmüller, M. Arenz +205
We report on the neutrino mass measurement result from the first four-week science run of the Karlsruhe Tritium Neutrino experiment KATRIN in spring 2019. Beta-decay electrons from…
Tritium beta decay with additional emission of new light bosons
Giorgio Arcadi, Julian Heeck, Florian Heizmann +5
We consider tritium beta decay with additional emission of light pseudoscalar or vector bosons coupling to electrons or neutrinos. The electron energy spectrum for all cases is eva…
