Neutrinoless Double Beta Decay: 2015 Review

Figure 19

(a) Allowed regions for as a function of with constraints given by the oscillation parameters. The darker regions show the spread induced by Majorana phase variations, while the light shaded areas correspond to the regions due to error propagation of the uncertainties on the oscillation parameters. (b) Constraints from cosmological surveys are added to those from oscillations. Different CL contours are shown for both hierarchies. Notice that the region for the case is not present, being the scenario disfavored at this confidence level. The dashed band signifies the 95% CL excluded region coming from [136]. Figure from [211].
