Δ isobars and nuclear saturation

NUCLEAR STRUCTURE ^2,3H, ^3,4He; calculated binding energies, charge radii at LO, NLO, and NNLO with and without the Δ(1232) isobar as function of momentum cutoff values of 450 and 500 MeV. ⁴He, ¹⁶O, ⁴⁰Ca; calculated ground-state energies per nucleon and charge radii computed with coupled cluster theory and the Δ-full potential at LO, NLO, and NNLO. ⁸He, ^16,22,24O, ^40,48Ca; calculated binding energies, charge radii, proton and neutron point radii, neutron skin. ⁴⁰Ca; calculated elastic charge form factor. Chiral effective field theory with inclusion of the Δ-isobar Δ(1232) degree of freedom at all orders up to next-to-next-to-leading order (NNLO). Comparison with experimental data.
