Double beta decay: The future

The future experiments being assembled or proposed to search for Double Beta Decay are presented and discussed with peculiar focus on the searches for the neutrinoless channel. Extension to larger masses of experiments presently 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 beta decay candidate nuclei. The potentialities of the various techniques and the expected sensitivities, as quoted by the authors by simulation or on the basis of the present performance of the running experiments are reported, compared and discussed.
