Effective field theory of nuclear forces

WebApr 12, 2024 · Standard nuclear physics methods like relativistic mean field theory or chiral perturbation theory [2,3] can be used for this purpose (for a recent review we refer to ). These theories are effective field theories (EFTs) in the sense that they introduce nucleons and mesons as their basic fields, instead of the quarks and gluons of QCD. WebThis review briefly introduces the chiral effective field theory of nuclear forces and atomic nuclei. We discuss the status of the nuclear Hamiltonian derived in this framework and some recent applications in few-nucleon systems. We also introduce nuclear lattice simulations as a new tool to address the many-body problem and present some of the …
