The two-nucleon electromagnetic charge operator in chiral effective field theory (chiEFT) up to one loop
read the original abstract
The electromagnetic charge operator in a two-nucleon system is derived in chiral effective field theory ($\chi$EFT) up to order $e\, Q$ (or N4LO), where $Q$ denotes the low-momentum scale and $e$ is the electric charge. The specific form of the N3LO and N4LO corrections from, respectively, one-pion-exchange and two-pion-exchange depends on the off-the-energy-shell prescriptions adopted for the non-static terms in the corresponding potentials. We show that different prescriptions lead to unitarily equivalent potentials and accompanying charge operators. Thus, provided a consistent set is adopted, predictions for physical observables will remain unaffected by the non-uniqueness associated with these off-the-energy-shell effects.

Explicitly on-shell currents in relativistic mean field models
The 'off-shell ambiguity' in relativistic mean-field one-body currents is spurious when currents are defined via free-nucleon operators; the correct mapping (Eq. 26) is parametrization-independent and requires time-li...

Challenging chiral EFT with tritium beta decay
Chiral EFT predictions at N2LO for the tritium Gamow-Teller matrix element, with parameters fixed from scattering, overestimate the empirical value and indicate large higher-order corrections.

Ab initio QMC calculations with Norfolk chiral interactions give a larger Zemach radius for 6Li than atomic data and agreement for 9Be, tracing prior discrepancies to model-dependent magnetic radius inputs.
