“…From the half-life limit of the ordinary Majoron-emitting decay mode we obtain an upper limit of g ee < (0.8 − 1.6) × 10 −5 at 90% C.L., where the range of the upper limit corresponds to the theoretical range of the nuclear matrix elements [13,14]. This is the most stringent limit on g ee to date among all ββ decay nuclei [5,12,[15][16][17][18][19][20][21]. The previous best limit from a laboratory experiment was from NEMO-3 for 100 Mo: g ee < (3.5 − 8.5) × 10 −5 [19].…”

We present limits on Majoron-emitting neutrinoless double-beta decay modes based on an exposure of 112.3 days with 125 kg of 136 Xe. In particular, a lower limit on the ordinary (spectral index n = 1) Majoronemitting decay half-life of 136 Xe is obtained as T 0νχ 0 1/2 > 2.6 × 10 24 yr at 90% C.L., a factor of five more stringent than previous limits. The corresponding upper limit on the effective Majoron-neutrino coupling, using a range of available nuclear matrix calculations, is gee < (0.8 − 1.6) × 10 −5 . This excludes a previously unconstrained region of parameter space and strongly limits the possible contribution of ordinary Majoron emission modes to 0νββ decay for neutrino masses in the inverted hierarchy scheme.

Exploring the neutrinoless double beta decay in the inverted neutrino hierarchy with bolometric detectors

et al. 2014

Neutrinoless double beta decay (0νββ) is one of the most sensitive probes for physics beyond the Standard Model, providing unique information on the nature of neutrinos. In this paper we review the status and outlook for bolometric 0νββ decay searches. We summarize recent advances in background suppression demonstrated using bolometers with simultaneous readout of heat and light signals. We simulate several configurations of a future CUORE-like bolometer array which would utilize these improvements and present the sensitivity reach of a hypothetical next-generation bolometric 0νββ experiment. We demonstrate that a bolometric experiment with the isotope mass of about 1 ton is capable of reaching the sensitivity to the effective Majorana neutrino mass (|m ee |) of order 10-20 meV, thus completely exploring the so-called inverted neutrino mass hierarchy region. We highlight the main challenges and identify priorities for an R&D program addressing them.

Phase-space factors and half-life predictions for Majoron-emittingβ−β−decay

A complete calculation of phase space factors (PSF) for Majoron emitting 0νβ − β − decay modes is presented. The calculation makes use of exact Dirac wave functions with finite nuclear size and electron screening and includes life-times, single electron spectra, summed electron spectra, and angular electron correlations. Combining these results with recent interacting boson nuclear matrix elements (NME) we make half-life predictions for the the ordinary Majoron decay (spectral index n=1). Furthermore, comparing theoretical predictions with the obtained experimental lower bounds for this decay mode we are able to set limits on the effective Majoron-neutrino coupling constant g M ee .
