Statistical Analysis of future Neutrino Mass Experiments including Neutrino-less Double Beta Decay

Understand

We perform a statistical analysis with the prospective results of future experiments on neutrino-less double beta decay, direct searches for neutrino mass (KATRIN) and cosmological observations.

• Realistic errors are used and the nuclear matrix element uncertainty for neutrino-less double beta decay is also taken into account.
• Three benchmark scenarios are introduced, corresponding to quasi-degenerate, inverse hierarchical neutrinos, and an intermediate case.
• We investigate to what extend these scenarios can be reconstructed.
