Short range nucleon-nucleon interaction and QCD potential models

A short range N-N interaction theory that explains hadrons provides a natural foundation for the theory of nuclear physics. Non-relativistic QCD potential models are studied to determine if there is a simple explanation for the simple features of N-N interactions. Under the MIT bag model, the N-N interaction is defined as very attractive in the intermediate range and having unphysical long repulsion arising from the 6 quark confinement in the bag. The little bag model has the advantage of producing the one pion exchange tail of the N-N interaction besides the short distance repulsion. Short wave deuteron wave function demonstrates that the entire fall of the N-N potential at short distances is due to the dynamical structure of the nucleons in the deuteron with no additional fall from the exchange force. Finally, the one boson exchange potential, by far the best known N-N interaction is studied
