Constraints on the effective Majorana neutrino mass (mββ) vs. the lightest neutrino mass (mlightest). For the inverted (IH, green) and normal (NH, red) hierarchies the central dark band is derived from the best-fit neutrino oscillation parameters; the lighter outer band includes their 3σ uncertainties [38]. The horizontal bands delineated by the long-dashed black lines (a), the dashed beige lines (b), and the dot-dashed blue lines (c) are the range of 90% C.L. upper limits on mββ coming from (a) 130Te (CUORE-0 combined with Cuoricino), (b) 136Xe (EXO-200, KamLAND-Zen independently), and (c) 76Ge (combined limit from Gerda, IGEX, HDM). The vertical arrows aim to emphasize the range currently probed with each isotope. The horizontal, hashed grey band indicates the range of limits on mββ expected from CUORE assuming its target 90% C.L. lower limit half-life sensitivity of 9.5 × 1025 yr is attained.
