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 …

The observation of neutrinoless double beta decay (DBD) will have important
consequences. First it will signal that lepton number is not conserved and the neutrinos are …

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 theoretical and experimental issues relevant to neutrinoless double beta decay are
reviewed. The impact that a direct observation of this exotic process would have on …

The current status and some perspectives of the phenomenology of massive neutrinos is
reviewed. We start with the phenomenology of neutrino oscillations in vacuum and in matter …

In this article we analyze the nuclear matrix elements (NME) of the neutrinoless double beta
decays (0νββ) of the nuclei 48Ca, 76Ge, 82Se, 124Sn, 128Te, 130Te and 136Xe in the …

The role that neutrinos have played in the evolution of the Universe is the focus of one of the
most fascinating research areas that has stemmed from the interplay between cosmology …

We report the final result of the CUORICINO experiment. Operated between 2003 and 2008,
with a total exposure of 19.75 kg· y of 130Te, CUORICINO was able to set a lower bound on …

We review the basic mechanisms of neutrino mass generation and the corresponding
structure of the lepton mixing matrix. We summarize the status of three-neutrino oscillation …

The connection of neutrino physics with the neutrinoless double-beta decay is reviewed.
After presenting the current status of the Pontecorvo–Maki–Nakagawa–Sakata matrix and …
