Nuclear matter in the chiral quark soliton model with vector mesons
  We study the nuclear matter solution in the chiral quark soliton model coupled to $\rho$ and $\omega$ vector mesons based on the Wigner-Seitz approximation. It is shown that the vector mesons stabilize the soliton at high-density region. As a result, the saturation property and incompressibility are significantly improved.
