Abstract

We point out that the effective potential which accounts for the QCD trace anomaly in a chiral lagrangian can involve the σ and π fields as well as the glueball field. This modified potential is applied to nuclear matter and, although the new contribution involves a small parameter, it is found to significantly extend the range of possible solutions. This improves the shape of the saturation curve at equilibrium, while yielding reasonable values for the quantities of interest.
