WebApr 12, 2024 · The Skyrme model incorporates in a completely natural fashion several important features of strong interaction physics, like chiral symmetry and its breaking, the conservation of baryon number, or the extended character of nucleons. As a consequence of the latter, it also avoids short-distance singularities in nucleon–nucleon interactions. WebJul 10, 2024 · A major goal of nuclear theory is to explain the spectra and stability of nuclei in terms of effective many-body interactions amongst the nucleus' constituents-the nucleons, i.e., protons and neutrons. Such an approach, referred to below as the basic model of nuclear theory, is formulated in terms of point-like nucleons, which emerge as …
WebThe relativistic mean field (RMF) model of the nuclear matter equation of state was modified by including the effect of Pauli-blocking owing to quark exchange between the baryons. Different schemes of a chiral enhancement of the quark Pauli blocking was suggested according to the adopted density dependence of the dynamical quark mass. The … WebIn 1936, Bethe and Bacher [] reviewed rather extensive data, subject to experimental techniques of the day, available on the charge, weight, binding energy, size, spin, statistics and electromagnetic moments of nuclei and outlined the then current state of knowledge of nuclear physics.Radioactive decay had been extensively studied and experiments with …

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 …
