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 …

Neutrinos are the only particles in the Standard Model that could be Majorana fermions, that
is, completely neutral fermions that are their own antiparticles. The most sensitive known …

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 …

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 …

We present the results of a National Science Foundation Project Sco** Workshop, the
purpose of which was to assess the current status of calculations for the nuclear matrix …

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 …

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 …

We present a comprehensive investigation of few-nucleon systems as well as light and
medium-mass nuclei up to A= 48 using the current Low Energy Nuclear Physics …

We investigate neutrinoless double-beta decay (0 ν β β) in the minimal extension of the
standard model of particle physics, the ν SM, where gauge-singlet right-handed neutrinos …
