Reduced regulator dependence of neutron-matter predictions with perturbative chiral interactions Academic Article uri icon


  • We calculate the energy per particle in infinite neutron matter perturbatively using chiral N3LO (next-to-next-to-next-to-leading order) two-body potentials plus N2LO three-body forces. The cutoff dependence of the predictions is investigated by employing chiral interactions with different regulators. We find that the inclusion of three-nucleon forces, which are consistent with the applied two-nucleon interaction, leads to a strongly reduced regulator dependence of the results. 2013 American Physical Society.
