Nuclear-matter equation of state with consistent two- and three-body perturbative chiral interactions
Nuclear-matter equation of state with consistent two- and three-body perturbative chiral interactions
We compute the energy per particle of infinite symmetric nuclear matter from chiral N$^{3}\mathrm{LO}$ (next-to-next-to-next-to-leading order) two-body potentials plus N$^{2}\mathrm{LO}$ three-body forces. The low-energy constants of the chiral three-nucleon force that cannot be constrained by two-body observables are fitted to reproduce the triton binding energy and the $^{3}\mathrm{H}$-$^{3}\mathrm{He}$ Gamow-Teller transition …
