Description
While neutrino oscillation experiments have finally provided the incontrovertible evidence that neutrinos mix and have finite masses the absolute scale and ordering of the masses of the three generations as well as charge conjugation and lepton number conservation properties are still unknown.
In this scenario, a unique role is played by the Neutrinoless Double Beta Decay searches: these experiments can probe lepton number conservation, investigate the Dirac/Majorana nature of the neutrinos and their absolute mass scale (hierarchy problem) with unprecedented sensitivity.
Today Neutrinoless Double Beta Decay faces a new era where large scale experiments with a sensitivity approaching the so-called degenerate-hierarchy region are nearly ready to start and where the challenge for the next future is the construction of detectors characterized by a tonne-scale size and an incredibly low background, to fully probe the inverted-hierarchy region.
Recent results and future projects are discussed.
