The future experiments being assembled or proposed to search for Double Bet
a Decay are presented and discussed with peculiar focus on the searches for
the neutrinoless channel. Extension to larger masses of experiments presen
tly running with conventional detectors is considered. Special attention is
devoted to new techniques, which could allow to overcome the limitation of
the presently running experiments and provide an ample choice of double be
ta decay candidate nuclei. The potentialities of the various techniques and
the expected sensitivities, as quoted by the authors by simulation or on t
he basis of the present performance of the running experiments are reported
, compared and discussed.
