Effective field theory approach to nuclear matter

摘要

The two- and three-nucleon interactions derived in chiral effective field theory at next-to-next-to-leading order are used to obtain the binding energy of nuclear matter. Saturation is found at a binding energy per particle EA=-16.2±0.3 MeV and a Fermi momentum k _F=1.30±0. 03fm ~(-1), where the uncertainty is due to the cut-off dependence of the two-nucleon interaction. The sensitivity of these values to the three-nucleon force is also studied.
