“…The combined limit of CUORE, CUORE-0 and Cuoricino on the 130 Te 0νββ half-life is 1.5 • 10 25 yr [69]. It follows the corresponding limits in 136 Xe and 76 Ge, namely 1.1 • 10 26 yr at 90% C. L. by the KamLAND-Zen Collaboration [79] and 8.0 • 10 25 yr at 90% C. L. by the GERDA Collaboration [80]. Eventually, CUORE is expected to raise its half-life limit sensitivity at 9.0 • 10 25 yr at 90% C. L. [81], therefore ensuring the central role played by thermal detectors in the forthcoming future.…”

“…Unfortunately each of these requests implies often contradictory constraints and a compromise solution is usually unavoidable. As a result, the list of isotopes commonly under study includes [4]: 48 Ca, 76 Ge, 82 Se, 96 Zr, 100 Mo, 116 Cd, 130 Te, 136 Xe, and 150 Nd. Among these, 130 Te presents important advantages (Table 1) and it results to be a very favorable choice.…”

Neutrinoless Double Beta Decay Experiments With TeO2 Low-Temperature Detectors

Neutrinoless double beta decay (0νββ) is a powerful tool to investigate Lepton Number Violation (LNV), and the only practical way to assess the nature of the neutrinos. It can therefore provide unique information about the Physics Beyond the Standard Model. If observed, 0νββ would unambiguously demonstrate that neutrinos are Majorana particles and would provide a precise measurement of their mass. Among the many experimental techniques used in the search for this rare process, low-temperature detectors represent one of the most promising choices: they show an excellent energy resolution and can scale to very large masses. In this work, we review the most relevant experiments based on TeO 2 bolometers that have been developed and taking data at the Laboratori Nazionali del Gran Sasso (LNGS), Italy, since the early 90's. This 30-years-old effort has led to the design and construction of the CUORE detector, currently taking data at LNGS. The use of low-temperature detectors allows to study the 0νββ of 130 Te on both ground and excited states, and to explore different decay mechanisms ("standard" light neutrino exchange, Majoron emission, …). At the same time, the investigation of other rare nuclear physics processes is also possible, such as the two-neutrino double beta decay of 130 Te as well as the rare decays ( 120 Te and 123 Te). Next generation bolometric experiments anticipate top leading sensitivities. The corresponding challenges in the development of ton-scale, low background detectors are highlighted.

“…One also expects similar suppression in this extradimensional model for B-and L-violating decays involving trinucleon initial states, such as ppp → ℓ + π + π + and ppn → ℓ + π + , mediated by 10-fermion operators, or ppp → ℓ + ℓ ′+ ℓ ′′+ and ppn → ℓ + ℓ ′+ν , mediated by 12-fermion operators. Recent experimental bounds on trinucleon decays include [65,66].…”

It is known that limits on baryon-violating nucleon decays do not, in general, imply corresponding suppression of n −n transitions. In the context of a model with fermions propagating in higher dimensions, we investigate a related question, namely the implications of limits on ∆L = −1 proton and bound neutron decays mediated by four-fermion operators for rates of nucleon decays mediated by k-fermion operators with k = 6 and k = 8. These include a variety of nucleon and dinucleon decays to dilepton and trilepton final states with ∆L = −3, −2, 1, and 2. We carry out a lowenergy effective field theory analysis of relevant operators for these decays and show that, in this extra-dimensional model, the rates for these decays are strongly suppressed and hence are in accord with experimental limits.

“…Baryon number violation by more than two units has not been well explored, with sparse theoretical [119] and experimental [120][121][122][123] studies. As mentioned before, one particularly well-motivated case that falls into this category is ∆B = ∆L = 3, as mediated in the SM by non-perturbative electroweak instantons.…”

Proton decay, and the decay of nucleons in general, constitutes one of the most sensitive probes of high-scale physics beyond the Standard Model. Most of the existing nucleon decay searches have focused primarily on two-body decay channels, motivated by Grand Unified Theories and supersymmetry. However, many higher-dimensional operators violating baryon number by one unit, ∆B = 1, induce multi-body nucleon decay channels, which have been only weakly constrained thus far. While direct searches for all such possible channels are desirable, they are highly impractical. In light of this, we argue that inclusive nucleon decay searches, N → X+anything (where X is a light Standard Model particle with an unknown energy distribution), are particularly valuable, as are model-independent and invisible nucleon decay searches such as n → invisible. We comment on complementarity and opportunities for such searches in the current as well as upcoming largescale experiments Super-Kamiokande, Hyper-Kamiokande, JUNO, and DUNE. Similar arguments apply to ∆B > 1 processes, which kinematically allow for even more involved final states and are essentially unexplored experimentally.
