Webnuclei, eventually combining well-developed many-body techniques with the forces from chiral nuclear EFT. Another way to approach light and medium-heavy nuclei is based on simulation techniques because they are so successfully utilized in lattice QCD (5) to calculate the properties of protons, neutrons, and many other hadrons. WebJun 6, 2005 · Using SU(3) chiral perturbation theory, we calculate the density-dependent complex mean field U Σ (k f) + i W Σ (k f) of a Σ hyperon in isospin-symmetric nuclear matter. The leading long-range Σ N interaction arises from one-kaon exchange and from two-pion exchange with a Σ or a Λ hyperon in the intermediate state. We find from the Σ …
