Theory Framework

Nuclear electromagnetic currents derived in a chiral-effective-field-theory framework including explicit nucleons, Δ isobars, and pions up to N2LO, i.e. ignoring loop corrections, are used in a study of neutron radiative captures on protons and deuterons at thermal energies, and of A=2 and 3 nuclei magnetic moments. With the strengths of the Δ-excitation currents determined to reproduce the n-p cross section and isovector combination of the trinucleon magnetic moments, we find that the cross section and photon circular polarization parameter, measured respectively in n-d and [Formula: see text] processes, are significantly underpredicted by theory.
