Abstract
A correct description of the saturation properties of nuclear matter has remained an unresolved issue for a very long time. The Brueckner-Bethe-Goldstone expansion supplies a converged result for the energy per particle in the relevant density range, for a given realistic interaction, at the level of three hole-line contributions. The intrinsic structure of the nucleon and its related strong coupling to the Δ isobar inevitably require the consideration of three-body forces. When three-body forces are considered in variational calculations it is possible to achieve better saturation properties only when an ad hoc repulsive short-range component of this three-body force is added.
