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.

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