Description
Chiral effective field theory is a well-known tool for the description of nuclear physics in the low-energy sector. Far below the pion production threshold, one can use the Goldstone-boson nature of the exchanged pions to obtain the most general expansion of the nuclear forces in powers of low momenta, divided by a breakdown scale of the theory of order 600 MeV. In the last three decades, chiral two- and three-nucleon forces have been worked out to very high order. In my talk, I will review recent applications of these forces to the description of nuclear structure within LENPIC (Low Energy Nuclear Physics International Collaboration). I will also give an update on the construction of the three-nucleon forces up to next-to-next-to-next-to-leading order (N3LO) in chiral expansion, and will show how to construct them in a way that preserves chiral symmetry.
