1307.1889 (Arianna Carbone et al.)

Symmetric nuclear matter with chiral three-nucleon forces in the
self-consistent Green's functions approach

Arianna Carbone, Arnau Rios, Artur Polls
We present calculations for symmetric nuclear matter using chiral nuclear interactions within the Self-Consistent Green's Functions approach in the ladder approximation. Three-body forces are included via effective one-body and two-body interactions, computed from an uncorrelated average over a third particle. We discuss the effect of the three-body forces on the total energy, computed with an extended Galitskii-Migdal-Koltun sum-rule, as well as on single-particle properties. Saturation properties are substantially improved when three-body forces are included, but there is still some underlying dependence on the renormalization scale.
