Abstract: | Neutrinoless double beta-decay (0vbb-decay) is the most promising approach to distinguish between the possibilities of a Dirac or a Majorana nature of neutrinos. Additionally, a measurement of the half-life of 0vbb-decay can give information on the absolute mass scale of neutrinos. At the moment HPGe detectors yield the most sensitive limits on this Lepton-number violating process. The segmentation of HPGe detectors increases the experimental sensitivity by allowing the reconstruction of event topologies. The successful operation of prototype detectors submerged in cryoliquid demonstrates the viability of this experimental approach. |
