Abstract

We perform a comprehensive study of the 3+3 Type-I seesaw model for a broad range of right-handed mass scales (from keV to 10 TeV). We take into account and, in some cases, update the constraints from a large number of high- and low-energy experiments and study the implications on neutrino-less double beta (0νββ) decay experiments. We illustrate our findings through profile likelihood plots for the half-life T_1/2^0ν and two-dimensional plots correlating T_1/2^0ν to neutrino masses. We find that in this simple class of models for Majorana neutrino masses, current and next-generation 0νββ decay experiments have a broad discovery potential in both the normal and inverted orderings of the spectrum of light active neutrinos.
