Di- and multibaryon clusters in nuclei: A nontraditional view on the nature of nuclear forces and on the structure of nuclei

Abstract

Numerous experimental data that come from experiments performed over the past decades at various accelerators worldwide and which favor the existence in ordinary nuclei of multibaryon (di-, tri-, etc.) multiquark clusters, which are responsible for the majority of nuclear- and hadron-physics processes accompanied by a high momentumor energy transfer to the nucleus involved, are considered. In contrast to what is done within a great many phenomenological multiquark models, the multibaryon concept developed in the present study is constructed on the basis of the original model of nucleon-nucleon forces that includes a dibaryon component as an important and indispensable element of a basic theory. The di- and multibaryon concept of nuclear forces is used as a basis for taking a fresh look at many nuclear-physics phenomena that, traditionally, have never been associated with manifestations of quark-gluon degrees of freedom. Numerous implications of the existence of multibaryons in nuclei for describing basic nuclearphysics phenomena and processes are discussed.
