Neutrinoless Double β+/EC Decays by Jukka Maalampi, Jouni Suhonen

“…The relation of neutrino masses to neutrino oscillations and the nuclear double beta decay is highlighted. In particular, the neutrinoless β+β+, β+EC, and resonant ECEC decays are investigated using microscopic nuclear models. …”

Convoluted ν-Signals on 114Cd Isotope from Astrophysical and Laboratory Neutrino Sources by Vaitsa Tsakstara

“…At first, we evaluate scattering cross sections of low, and intermediate-energy neutrinos scattered off the 114 Cd isotope, the most abundant Cd isotope present also in the COBRA detector (CdTe and CdZnTe materials) which aims to search for double beta decay events and neutrino observations at Gran Sasso laboratory (LNGS). …”

Non-holomorphic modular S 4 lepton flavour models by Gui-Jun Ding, Jun-Nan Lu, S.T. Petcov, Bu-Yao Qu

“…We identify the phenomenologically viable models and obtain predictions for each of these models for the neutrino mass ordering, the absolute neutrino mass scale, the Dirac and Majorana CP-violation phases and, correspondingly, for the sum of neutrino masses and the neutrinoless double beta decay effective Majorana mass. We comment on how these models can be tested and conclude that they are all falsifiable. …”

Astrophysical insights into magnetic Penrose process around parameterized Konoplya–Rezzolla–Zhidenko black hole by Tursunali Xamidov, Sanjar Shaymatov, Pankaj Sheoran, Bobomurat Ahmedov

“…Additionally, we explore the astrophysical implications of the MPP by deriving the maximum energy of a proton escaping from the KRZ parameterized BH due to the beta decay of a free neutron near the horizon. Our results show that negative $$\delta _2$$ δ 2 values require stronger magnetic fields to achieve equivalent energy levels for high-energy protons, providing deeper insights into high-energy astrophysical phenomena around the parameterized BH.…”

“…Designed as a multipurpose neutrino experiment, the primary goal of SNO+ is a search for the neutrinoless double-beta decay (0νββ) of 130Te. In Phase I, the detector will be loaded with 0.3% natural tellurium, corresponding to nearly 800 kg of 130Te, with an expected effective Majorana neutrino mass sensitivity in the region of 55–133 meV, just above the inverted mass hierarchy. …”

Correlating 0νββ decays and flavor observables in leptoquark models by S. Fajfer, L. P. S. Leal, O. Sumensari, R. Zukanovich Funchal

“…By using leptoquark couplings fixed by neutrino data, we predict additional contributions to neutrinoless double-beta decays (0νββ), which are chirality enhanced and compete with the standard contributions from the Majorana masses. …”
