We derive the leading two-pion exchange contributions to the two-nucleon electromagnetic current operator in the framework of chiral effective field theory using the method of unitary transformation. Explicit results for the current and charge densities are given in momentum and coordinate space.

  1. Challenging chiral EFT with tritium beta decay

    nucl-th 2026-06 unverdicted novelty 6.0

    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.

  2. Quantum Monte Carlo calculations of Zemach moments in $A\leq 9$ nuclei

    nucl-th 2026-06 unverdicted novelty 6.0

    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.

  3. Can the strong interactions between hadrons be determined using femtoscopy?

    nucl-th 2025-04 unverdicted novelty 3.0

    The universality assumption in the Koonin-Pratt formula for femtoscopic correlations introduces potentially large intrinsic uncertainty when extracting strong interactions between hadrons like nucleons.
