Description
In this talk we discuss the impact of cosmological measurements on future searches for neutrinoless double-beta decay (0nbb). The fundamental importance of 0nbb for particle physics -- in particular for neutrino physics -- is well known and many efforts are underway to push the experimental sensitivity to values of the half-life of the process above 10^27 years. Current cosmological results already allow us to place stringent constraints on Majorana's effective mass, i.e. the electron-type mass of ordinary neutrinos; tighter limits and more precise information are expected in the near future. In this context, we quantify the probability of discovering 0nbb for next-generation experiments by updating and extending a broad line of investigation we have conducted over the years*. We minimize assumptions on unknown parameters, such as Majorana phases, and present a new graphical representation of the results, of relevance to the 0nbb community.
