  We present a model for describing nuclear matter at finite density based on
quarks interacting with chiral fields, \sigma and \pi and with vector mesons
introduced as massive gauge fields. The chiral Lagrangian includes a
logarithmic potential, associated with the breaking of scale invariance. We
provide results for the soliton in vacuum and at finite density, using the
Wigner-Seitz approximation. We show that the model can reach higher densities
respect to the linear-\sigma model and that the introduction of vector mesons
allows to obtain saturation. This result was never obtained before in similar
approaches.
