Abstract We calculate the equation of state of isospin-symmetric nuclear matter in the three-loop approximation of chiral perturbation theory. The contributions to the energy per particle E (k f ) from one- and two-pion exchange diagrams are ordered in powers of the Fermi momentum kf (modulo functions of kf/mπ). It is demonstrated that, already at order O (k f 4 ) , two-pion exchange produces realistic nuclear binding. The underlying saturation mechanism is surprisingly simple (in the chiral… Expand
