摘要

We study equation of state of cold and dense baryon matter within the relativistic mean-field framework with hadron masses and coupling constants dependent on the mean scalar field. Previously constructed models with included hyperons and Δ isobars are extended taking into account possibility of the condensation of charged ρ mesons. We demonstrate that the results obtained in the models with the charged ρ-meson condensation taken into account exhibit a strong model dependence. In some of our (so-called KVORcut-based) models the charged ρ condensation does not significantly affect the value of the neutron star maximum mass. In other (so called MKVOR-based) models the neutron star maximum mass decreases substantially. All thus constructed models pass the observational constraint on the minimal value of the maximum neutron star mass.
