Delta isobars and nuclear saturation

We construct a nuclear interaction in chiral effective field theory with explicit inclusion of the \(\Delta\)-isobar \(\Delta(1232)\) degree of freedom at all orders up to next-to-next-to-leading order (NNLO). We use pion-nucleon (\(\pi N\)) low-energy constants (LECs) from a Roy-Steiner analysis of...
