Present Status and Future Perspectives of the NEXT Experiment
Figure 2
The left image shows the normal (a) and inverted (b) mass orderings. The electron, muon, and tau flavor content of each neutrino mass eigenstate are shown via the red, green, and blue fractions, respectively. , while in the normal ordering and in the inverted ordering. The right plot shows the effective neutrino Majorana mass, , as a function of the lightest neutrino mass, . The green band corresponds to the inverse hierarchy of neutrino masses, whereas the red corresponds to the normal ordering. The upper bound on the lightest neutrino mass comes from cosmological bounds; the bound on the effective Majorana mass comes from constraints.
