Recent progress in description of NN–scattering with the dibaryon model of nuclear forces

Abstract

The recent results in description of elastic and inelastic nucleon-nucleon scattering within the dibaryon model of nuclear forces are reviewed. This original model taking into account non-nucleonic degrees of freedom is based on the special mechanism including an exchange by an intermediate six quark state. A good description of the partial phase shifts and inelasticities is found for the main lowest partial NN configurations in a wide energy range from zero up to 0.6–1 GeV. The model gives the resonances in each NN-configuration as well, the parameters of which are compared with the data found from recent experiments on single- and double-pion production and partial wave analysis.
