Neutrinoless Double Beta Decay: 2015 Review

Figure 20

Constraints from cosmological surveys are added to those from oscillations in the representation of as a function of the lightest neutrino mass. The dotted contours represent the regions allowed considering oscillations only. The shaded areas show the effect of the inclusion of cosmological constraints at different CL. The horizontal bands correspond to the expected sensitivity for future experiments. Figure from [211].
