WebI describe how lessons from Pionless EFT are being applied to the construction of a properly renormalized Chiral EFT. Ever since quantum field theory was first applied to the derivation of nuclear forces in the mid … WebFirst, chiral effective field theory (χ 𝜒 \chi italic_χ EFT) provides a natural hierarchy to define two-nucleon (NN), three-nucleon (NNN), and even four-nucleon interactions. Second, ab initio methods have been developed capable to test these interactions for light nuclei.

WebJun 28, 2024 · Chiral EFT, based on the intrinsic chiral symmetries of QCD, is an approximation of QCD that uses effective degrees of freedom such as nucleons, pions, and other hadrons. Using a pertubative approach, it provides a systematic framework to construct the two-, three-, and many-nucleon interactions necessary to solve nuclear … 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 ...
