Summary
The energy per particle of symmetric nuclear matter and pure neutron matter is
calculated using the many-body Brueckner-Hartree-Fock approach and employ-
ing the Chiral Next-to-next-to-next-to leading order (N3LO) nucleon-nucleon
(NN) potential, supplemented with various parametrizations of the Chiral Next-
to-next-to leading order (N2LO) three-nucleon interaction. Such combination
is able to reproduce several observables of the physics of light nuclei for suit-
able choices of the parameters entering in the three-nucleon interaction. We
find that some of these parametrizations provide a satisfactory saturation point
of symmetric nuclear matter and values of the symmetry energy and its slope
parameter L in very good agreement with those extracted from various nuclear
experimental data. Thus, our results represent a significant step toward a uni-
fied description of few- and many-body nuclear systems starting from two- and
three-nucleon interactions based on the symmetries of QCD.
