WebApr 10, 2024 · The currently most established approach is based on chiral effective field theory (휒 EFT) . This theory allows one to derive nuclear interactions via a perturbative expansion in quark masses and in the three momenta of the nucleons. It offers a natural explanation of the observed hierarchy of nuclear forces, in which two-nucleon interactions ...
