Dibaryon Concept for Short-Range 2N and 3N Forces: Consequences for Hadronic and Nuclear Physics

The short-range aspects of 2N and 3N nuclear interactions are considered in light of numerous novel experimental data obtained in JLab, BNL, Mainz, etc. Many of these new experimental results contradict strongly to the traditional models for short-range (or high-momentum) components of nuclear forces and therefore require a novel understanding within new models alternative to the traditional (one-boson-exchange) ones. At the NN distances r _{N N} < 1 fm the nucleon quark cores get overlapped with each other and thus the generation of the common six-quark bag is very likely. So, the dibaryon concept considers the generation of the intermediate six-quark bag dressed with meson (predominantly the scalar-isoscalar σ-meson) clouds as a driving mechanism for short-range nuclear force. Numerous predictions of the above dibaryon model are considered in the paper.
