Neutrinoless Double Beta Decay: 2015 Review
Advances in High Energy Physics, 2016 The discovery of neutrino masses through the observation of oscillations boosted the importance of neutrinoless double beta decay (0νββ). In this paper, we review the main features of this process, underlining its key role from both the experimental and ...

First limits on double beta decays in $$^\mathbf{232}$$ 232 Th
European Physical Journal C: Particles and Fields, 2020 As one of the primordial radioactive isotopes, $$^{232}\mathrm{Th}$$ 232Th mainly undergoes $$\alpha $$ α -decay with a half-life of $$1.402\cdot 10^{10}$$ 1.402·1010 years. However, it is also one of 35 double beta decay candidates in which the single $

Rare weak decays and nuclear structure
EPJ Web of Conferences, 2014 Weak interactions cause the atomic nuclei to decay via beta and double beta decays. Double beta decays are extremely rare since they are weak-interaction processes of the second order. Also (single) beta decays can be extremely rare.

Loop-enhanced rate of neutrinoless double beta decay
Journal of High Energy Physics, 2019 Neutrino masses can be generated radiatively. In such scenarios their masses are calculated by evaluating a self-energy diagram with vanishing external momentum, i.e. taking only the leading order term in a momentum expansion.

Neutrinoless Double Beta Decay within QRPA with Proton-Neutron Pairing [PDF]
, 1996 We have investigated the role of proton-neutron pairing in the context of the Quasiparticle Random Phase approximation formalism. This way the neutrinoless double beta decay matrix elements of the experimentally interesting A= 48, 76, 82, 96, 100, 116 ...

Double-beta decay: Present status [PDF]
Physics of Atomic Nuclei, 2009 The present status of double beta decay experiments (including the search for $2 ^{+}$, EC$ ^{+}$ and ECEC processes) are reviewed. The results of the most sensitive experiments are discussed. Average and recommended half-life values for two-neutrino double beta decay are presented.
