“…At the same time the lower limits for the half-lives of the 0νββ decay mode keep steadily increasing [3]. Important nuclei for the present and future 0νββ experiments are 76 Ge (the GERDA experiment [6], and in the future GERDA and Majorana [7]), 82 Se (the NEMO-3 experiment [8], and in the future SuperNEMO [9] and MOON [10]), 96 Zr (the NEMO-3 experiment [11]), 100 Mo (the NEMO-3 experiment [12], and in the future AMoRE [13], LUMINEU [14], CUPID [15], MOON [10]), 116 Cd (the NEMO-3 experiment [16], and in the future AURORA [17], COBRA [18]), 130 Te (the CUORE experiment [19], and in the future CUORE and SNO+ [20]), and 136 Xe (the EXO [21] and KamLAND-Zen [22] experiments, and in the future NEXT [23] and PandaX-III [24]). …”

Impact of the quenching of gA on the sensitivity of 0νββ experiments

Detection of the neutrinoless ββ (0νββ) decay is of high priority in the particle-and neutrinophysics communities. The detectability of this decay mode is strongly influenced by the value of the weak axial-vector coupling constant gA. The recent nuclear-model analyses of β and ββ decays suggest that the value of gA could be dramatically quenched, reaching ratios of g free A /gA ≈ 4, where g free A = 1.27 is the free, neutron-decay, value of gA. The effects of this quenching appear devastating for the sensitivity of the present and future 0νββ experiments since the 4th power of this ratio scales the 0νββ half-lives. This, in turn, could lead to some two orders of magnitude less sensitivity for the 0νββ experiments. In the present article it is shown that by using a consistent approach to both the two-neutrino ββ and 0νββ decays by the proton-neutron quasiparticle random-phase approximation (pnQRPA), the feared two-orders-of-magnitude reduction in the sensitivity of the 0νββ experiments actually shrinks to a reduction by factors in the range 2 − 6. This certainly has dramatic consequences for the potential to detect the 0νββ decay.PACS numbers: 21.60.Jz, 23.40.Hc, 27.50.+e, 27.60.+j Keywords: Detectability of the neutrinoless double beta decay, nuclear matrix elements, quenching of the axial-vector coupling strength, sensitivity of the double-beta experiments

“…This allows for discrimination between the processes. Experimental searches for ββ decay mediated by emission of one or two Majorons (0νββχ ) have been performed by the Heidelberg-Moscow experiment (HdM) for 76 Ge [8,9]; by Nemo-2 and Nemo-3 for 100 Mo, 116 Cd, 82 Se, 96 Zr, 130 Te [10][11][12][13][14][15]; by ELEGANT V for 100 Mo [16]; by DAMA [17], KAMland-Zen [18] and Exo-200 [19] for 136 Xe. None of these experiments have seen an excess of events that could be interpreted as a Majoron signal; they reported lower limits on the half-lives of the processes that involve Majoron emission.…”

A search for neutrinoless ββ decay processes accompanied with Majoron emission has been performed a e-mail: gerda-eb@mpi-hd.mpg.de using data collected during Phase I of the GERmanium Detector Array (GERDA) experiment at the Laboratori Nazionali del Gran Sasso of INFN (Italy). Processes with 123 416 Page 2 of 12 Eur. Phys. J. C (2015) 75 :416 spectral indices n = 1, 2, 3, 7 were searched for. No signals were found and lower limits of the order of 10 23 yr on their half-lives were derived, yielding substantially improved results compared to previous experiments with 76 Ge. A new result for the half-life of the neutrino-accompanied ββ decay of 76 Ge with significantly reduced uncertainties is also given, resulting in T 2ν 1/2 = (1.926 ± 0.094) × 10 21 yr.

“…The former has provided information on the neutrino mass square differences ∆m 2 21 and ∆m 2 31 , mixing angles θ 12 , θ 23 and θ 13 and possible hierarchies in the neutrino mass spectrum [11]. In addition to hinting on the Majorana nature of neutrinos, the latter has also ascertained the role of various mechanism in different gauge theoretical models [12].…”
