This review demonstrates the unique role of the neutrino by discussing in detail the physics
of and with neutrinos. We deal with neutrino sources, neutrino oscillations, absolute masses …

Since the discovery of neutrino oscillations, we know that neutrinos have non-zero mass.
However, the absolute neutrino-mass scale remains unknown. Here we report the upper …

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 …

In this contribution, we review the status and perspectives of direct neutrino mass
experiments, which investigate the kinematics of β‐decays of specific isotopes (3H, 187Re …

This paper reports on the improved Mainz experiment on tritium β spectroscopy which yields
a 10 times higher signal to background ratio than before. The main experimental effects and …

The European Particle Physics Strategy Update (EPPSU) process takes a bottom-up
approach, whereby the community is first invited to submit proposals (also called inputs) for …

We report the results of the second measurement campaign of the Karlsruhe Tritium
Neutrino (KATRIN) experiment. KATRIN probes the effective electron anti-neutrino mass …

We present the results of the light sterile neutrino search from the second Karlsruhe Tritium
Neutrino (KATRIN) measurement campaign in 2019. Approaching nominal activity, 3.76× 10 …

Results of the “Troitsk ν-mass” experiment on the search for the neutrino rest mass in the
tritium beta-decay are presented. Study of time dependence of anomalous, bump-like …

When Kai Zuber's pioneering text on neutrinos was published in 2003, the author correctly
predicted that the field would see tremendous growth in the immediate future. In that book …
