]]>In neutrinoless double-$\beta $ decay such as ${}^{136}$Xe to ${}^{136}$Ba, two neutrons become two protons, thus rearranging the occupancy of protons and neutrons in the ground states of the parent and daughter nuclei. From precision measurements of the cross sections of single-neutron adding and -removing reactions, the authors extract the change in ground-state neutron occupancies between ${}^{136}$Xe and ${}^{136}$Ba. Along with recent results on the proton occupancies, the new experimental neutron occupancies disagree with those used in existing theoretical calculations of the rate of this elusive $\beta $-decay mode, and provide a basis for improved estimates of the uncertainties for new calculations.

]]>The authors consider contributions to parity-violating electron-proton scattering from two-photon exchange, where the electromagnetic interaction of the nucleon has a parity-violating component. Unlike the standard short-ranged weak interaction conveyed by a massive $Z$ boson, the considered mechanism induces novel long-range parity-violating forces. This is relevant for upcoming measurements at electron accelerator facilities at the University of Mainz and Jefferson Laboratory, including the Q-Weak experiment. The results will allow access to the weak charge of the nucleon and thereby, potentially, to physics beyond the Standard Model.
