A plausible explanation for the lightness of neutrino masses is that neutrinos are massless at
tree level, with their mass (typically Majorana) being generated radiatively at one or more …

The discovery of neutrino masses through the observation of oscillations boosted the
importance of neutrinoless double beta decay (0νββ). In this paper, we review the main …

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 …

The Review summarizes much of particle physics and cosmology. Using data from previous
editions, plus 2,873 new measurements from 758 papers, we list, evaluate, and average …

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP
(search for hidden particles) experiment is intended to hunt for new physics in the largely …

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 …

We review the collider phenomenology of neutrino physics and the synergetic aspects at
energy, intensity and cosmic frontiers to test the new physics behind the neutrino mass …

A discovery that neutrinos are Majorana fermions would have profound implications for
particle physics and cosmology. The Majorana character of neutrinos would make possible …
