Lower Bound on |U_{e3}|^2 from Single and Double Beta Decay Experiments

Abstract

We point out under the assumption of Majorana neutrinos that a lower bound on the MNS matrix element |U_{e3}|^2 can be derived by using constraint imposed by neutrinoless double beta decay experiments and by positive detection of neutrino mass by single beta decay experiments. We show that the lower bound exists in a narrow region of the ratio of the observables in these two experiments, <m>_{ββ}/<m>_β. It means that once the neutrino mass is detected in the bound-sensitive region one must soon observe signal in neutrinoless double beta decay experiments.
