Challenges in Double Beta Decay

Table 5

A selected list of the next generation experiments. Important features that characterize each experiment are indicated in the last column: refers to a good energy resolution while pulse shape analysis (PSA) stands for the capability to discriminate events topologies. The isotope mass, , reported here takes into account isotopic abundance and fiducial volume as described in Sections 7ā€“11.
