The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

The nature of dark matter and properties of neutrinos are among the most pressing issues in
contemporary particle physics. The dual-phase xenon time-projection chamber is the …

We propose the construction of LEGEND-1000, the ton-scale Large Enriched Germanium
Experiment for Neutrinoless $\beta\beta $ Decay. This international experiment is designed …

We propose a novel storage scheme for three-nucleon (3N) interaction matrix elements
relevant for the normal-ordered two-body approximation used extensively in ab initio …

We review the status and prospects of heavy-ion double charge exchange (HI-DCE)
reactions. Their important role for nuclear reaction, nuclear structure and double beta-decay …

The amplitude for the neutrinoless double β (0 ν β β) decay of the two-neutron system nn→
ppe-e-constitutes a key building block for nuclear-structure calculations of heavy nuclei …

The observation of neutrino oscillations and hence non-zero neutrino masses provided a
milestone in the search for physics beyond the Standard Model. But even though we now …

Starting from chiral nuclear interactions, we evaluate the contribution of the leading-order
contact transition operator to the nuclear matrix element (NME) of neutrinoless double-beta …

A bstract We present a method to determine the leading-order (LO) contact term contributing
to the nn→ ppe− e− amplitude through the exchange of light Majorana neutrinos. Our …

Nuclear weak decays provide important probes to fundamental symmetries in nature. A
precise description of these processes in atomic nuclei requires comprehensive knowledge …
