In the QMC model, light quarks in nonoverlapping nucleon and $\\Xi^-$ bags interact self-consistently with isoscalar-scalar ($\\sigma$), isoscalar-vector ($\\omega$), and isovector-vector ($\\rho$) mesons in the mean field approximation. The parameters of the model (quark-meson coupling constants and masses) are mostly fixed from the nuclear matter saturation properties.
