Neutrinos were proposed by W. Pauli as a remedy to explain
nuclear beta decay. Now they are essential in our understanding
of the Universe. In this talk I will show how Neutrino-less
Double Beta Decay has a key role in determining the Majorana
versus Dirac nature of neutrinos and as confirmation of neutrino
mass values different from zero, as proofed by neutrino oscillation
experiments. Neutrino-less Double Beta Decay studies require,
in particular, the use of high-energy resolution detectors such
as thermal detectors in low background observatories. The large
detector mass of some thermal detector, the low energy threshold
of a few keV and low background environment make such a kind of
experiment well suited for direct detection of galactic Dark
Matter particles and solar Axions.
