   Neutrinoless Double-Beta Decay: Status and Prospects

   Michelle J. Dolinski🇺🇸 · Alan W. P. Poon🇺🇸 · Werner Rodejohann🇩🇪

   Neutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition whose observation would have fundamental implications for neutrino physics, theories beyond the Standard Model and cosmology. In this review, we summarize the theoretical progress to understand this process, the expectations and implications under various particle physics models, as well as the nuclear physics challenges that affect the precise predictions of the decay half-life. We will also provide a synopsis of the current and future large-scale experiments that aim at discovering this process in physically well-motivated half-life ranges.

   Experiments in preparation for search for uranium ternary fission by means of nuclear track emulsion are summarized. The study will be focused on the possible involvement of the unstable nucleus ${}^8$Be in the suggested scenario of the collinear tri-partition in the fission.
