Neutron Matter at Next-to-Next-to-Next-to-Leading Order in Chiral Effective Field Theory
Neutron Matter at Next-to-Next-to-Next-to-Leading Order in Chiral Effective Field Theory
Neutron matter presents a unique system for chiral effective field theory (EFT), because all many-body forces among neutrons are predicted to next-to-next-to-next-to-leading order (N3LO). We present the first complete N3LO calculation of the neutron matter energy. This includes the subleading three-nucleon (3N) forces for the first time and all leading …
