WebFeb 5, 2024 · The past two decades have witnessed tremendous progress in the microscopic description of atomic nuclei. Within this approach, nuclei are described in terms of nucleons interacting via realistic two- and three-body forces, constrained to accurately reproduce a large body of data for few nucleons systems. 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.
