“…For a useful determination of the phase, even in this simplistic two-flavor model, a precision nearing 10% is required. Note that a similar analysis can be found in Reference [36] and a three-neutrinospecies example is presented in Reference [2].…”

“…Double beta decay searches with no final-state neutrinos have not reported positive signals so far [19], except in the most sensitive ( 76 Ge) detector to date (Heidelberg-Moscow experiment), where part of the collaboration has claimed a signal at > 4σ level [13], recently promoted to > 6σ level by a pulse-shape analysis [20]. This claim is still considered as controversial [19] and we shall discuss its implications with due care in the following sections. In any case, any claim or limit on the 0ν2β decay half-life (T 0ν 1/2 ) in a candidate nucleus constrains the effective Majorana mass (m ββ ) through the relation…”

“…The last row in Table IV shows the current experimental limits on the various half lives, as taken from the recent compilations [19,41]. It can be appreciated that, except for 76 Ge and 130 Te, current limits must be improved by about one order of magnitude (at least) in order to probe any of the cases in Table I.…”

Observables sensitive to absolute neutrino masses: A reappraisal after WMAP 3-year and first MINOS results

In the light of recent neutrino oscillation and non-oscillation data, we revisit the phenomenological constraints applicable to three observables sensitive to absolute neutrino masses: The effective neutrino mass in single beta decay (m β ); the effective Majorana neutrino mass in neutrinoless double beta decay (m ββ ); and the sum of neutrino masses in cosmology (Σ). In particular, we include the constraints coming from the first Main Injector Neutrino Oscillation Search (MINOS) data and from the Wilkinson Microwave Anisotropy Probe (WMAP) three-year (3y) data, as well as other relevant cosmological data and priors. We find that the largest neutrino squared mass difference is determined with a 15% accuracy (at 2σ) after adding MINOS to world data. We also find upper bounds on the sum of neutrino masses Σ ranging from ∼ 2 eV (WMAP-3y data only) to ∼ 0.2 eV (all cosmological data) at 2σ, in agreement with previous studies. In addition, we discuss the connection of such bounds with those placed on the matter power spectrum normalization parameter σ 8 . We show how the partial degeneracy between Σ and σ 8 in WMAP-3y data is broken by adding further cosmological data, and how the overall preference of such data for relatively high values of σ 8 pushes the upper bound of Σ in the sub-eV range. Finally, for various combination of data sets, we revisit the (in)compatibility between current Σ and m ββ constraints (and claims), and derive quantitative predictions for future single and double beta decay experiments.
