摘要：

A two-component formalism has been developed for the reactionmatrix in a nuclear medium in the case of nucleon-nucleon interaction taking into account additional non-nucleonic degrees of freedom. The approach is based on the dibaryon model of nucleon-nucleon interactions, which recently allowed description of partial NN scattering amplitudes for the channels with total angular momentum J <= 3 in a wide energy range from zero to 0.6-1 GeV, and also to successfully reproduce the positions of the known dibaryon resonances for a number of channels. The bound states in the nuclear medium that arise for such a model have been studied. An equation of state for symmetric nuclear matter has been calculated within the framework of the Brueckner-Hartree-Fock scheme.
