Abstract

We develop a nuclear mass model that is based on chiral effective field theory at next-to-next-to leading order. Nuclear binding energies are computed via the Hartree-Fock method using a Hamiltonian from delta-full chiral effective field theory. We employ Hartree-Fock emulators to adjust 11 low-energy constants in the chiral interaction to binding energies of 18 even-even nuclei. When applied to 107 even-even nuclei with mass numbers 16≤ A≤ 56 the chiral mass model exhibits an overall root-mean-square deviation of 3.5 MeV.
