Nuclear forces from EFT: Recent developments

Nuclear forces are considered based on chiral perturbation theory with and without explicit -isobar degrees of freedom. We discuss the subleading corrections to chiral three-nucleon forces in the -less formalism which contain no additional free parameters. In the formalism with explicit -isobar we present the complete next-to-next-to-leading order analysis of isospin-conserving and next-to-leading order analysis of isospinviolating nuclear forces. The perturbative expansion of nuclear forces in the -full case is shown to have much better convergence compared with the -less theory where the -resonance is integrated out and is encoded in certain low-energy constants.
