The influence of the enhanced vector meson sector on the properties of the matter of neutron stars

This paper gives an overview of the model of a neutron star with non-zero strangeness constructed within the framework of the nonlinear realization of the chiral $SU(3{)}_L\times SU(3{)}_R$ symmetry. The emphasis is put on the physical properties of the matter of a neutron star. The obtained solution is particularly aimed at the problem of the construction of a theoretical model of a neutron star matter with hyperons that will give high value of the maximum mass.
