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 interaction, which recently allowed to describe partial 𝑁𝑁 scattering amplitudes for the channels with total angular momentum 𝐽 ≤ 3 in a wide energy range fromzero to 0.6–1 GeV, and also to reproduce successfully 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 are studied. An equation of state for symmetric nuclear matter has been calculated within the framework of the Brueckner–Hartree–Fock scheme.
