Search for neutrinoless double beta decay

Understand

We review current experimental efforts to search for neutrinoless double beta decay (0$\nu\beta\beta$).

• A description of the selected leading experiments is given and the strongest recent results are compared in terms of achieved background indexes and limits on effective Majorana mass.
• A combined limit is also shown.
• The second part of the review covers next generation experiments, highlighting the challenges and new technologies that may be necessary to achieve a justifiable discovery potential.
