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 …

The nuclear matrix elements that govern the rate of neutrinoless double beta decay must be
accurately calculated if experiments are to reach their full potential. Theorists have been …

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 …

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 …

Most of the free parameters in the Standard Model (SM)—a quantum field theory which has
successfully elucidated the behaviors of strong, weak and electromagnetic interactions of all …

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 …

We review the particle physics aspects of neutrino-less double beta decay. This process can
be mediated by light massive Majorana neutrinos (standard interpretation) or by something …
