Abstract
Cosmology is making impressive progress and it is producing stringent bounds on the sum of the neutrino masses Σ, a parameter of great importance for the current laboratory experiments. In this letter, we exploit the potential relevance of the analysis of Palanque-Delabrouille et al. [JCAP 02 (2015) 045] to the neutrinoless double beta decay (0ν β β) search. This analysis indicates small values for the lightest neutrino mass, since the authors find Σ < 84 meV at 1σ C.L., and provides a 1σ preference for the normal hierarchy. The allowed values for the Majorana effective mass, probed by 0ν β β, turn out to be < 75 meV at 3σ C.L. and lower down to less than 02 meV at 1σ C.L. . If this indication is confirmed, the impact on the 0ν β β experiments will be tremendous since the possibility of detecting a signal will be out of the reach of the next generation of experiments.
