The Search for neutrinoless double beta-decay

Abstract

Observation of neutrinoless double beta decay would greatly enlarge our knowledge on neutrino properties. It would reveal the Majorana nature of neutrinos and could yield information on their mass hierarchy. Experimental strategies to search for neutrinoless double beta‐decay experiments are explained. The experiments with highest sensitivity in the past are discussed. The current status of experiments likely to deliver competitive data wi thin the next two years are presented.
