Neutrinoless double-beta decay provides a strong probe of physics beyond the standard model. The observation of such a decay would establish that the neutrino and anti-neutrino are the same particle - a so-called Majorana particle - and would help determine the absolute mass scale of the neutrino. In addition, it could provide insight into understanding lepton-number-violating processes,...
