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 …

The present experimental results on neutrino flavour oscillations provide evidence for non-
zero neutrino masses, but give no hint on their absolute mass scale, which is the target of …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

It is commonly assumed that the energy density of the Universe was dominated by radiation
between reheating after inflation and the onset of matter domination 54,000 years later …

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 …

The Majorana nature of neutrinos can be experimentally verified only via lepton-number
violating processes involving charged leptons. We study 36 lepton-number violating (LV) …

In the early universe, neutrinos are slightly coupled when electron–positron pairs annihilate
transferring their entropy to photons. This process originates non-thermal distortions on the …

A bstract We make a comparative study of the neutrinoless double beta decay constraints on
heavy sterile neutrinos versus other direct and indirect constraints from both lepton number …

A bstract Neutrino oscillations involving eV-scale neutrino mass states are investigated in
the context of global neutrino oscillation data including short and long-baseline accelerator …
