The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

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 …

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 …

We report new results from the search for neutrinoless double-beta decay in Te 130 with the
CUORE detector. This search benefits from a fourfold increase in exposure, lower trigger …

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 …

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 …

Neutrinoless double-beta decay, which is a very old and yet elusive process, is reviewed. Its
observation will signal that the lepton number is not conserved and that the neutrinos are …

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 …
