Аннотация: A two-component formalism has been developed for the reaction matrix 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 alloweddescription of partial NN scattering amplitudes for the channels with total angular momentum J ≤ 3 in awide energy range from zero to 0.6–1 GeV, and also to successfully reproduce the positions of the knowndibaryon 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.
