Neutrinoless double beta decay experiment
arXiv:2004.02510
Abstract
The search for neutrinoless double beta decay () is one of the key experiments for determining unresolved properties of neutrinos. Experimental observation of would provide a clear demonstration of the Majorana nature of neutrinos and a lepton number violating process in particle physics. This report is a brief review describing the process and its significance. The detector technologies used in the present and proposed experiments are compared among their recent experimental results. Moreover, the sensitivities for discovery in a number of present and proposed experiments are introduced.
