Abstract
In the framework of an effective derivative-coupling model with scalar and vector mesons coupled to the octet of baryons and leptonic degrees of freedom, we have calculated in detail the nuclear property known as the compressibility function, using the mean-field theory formalism and taking into account chemical equilibrium, baryon number and electric charge conservation. The parameters of the model are chosen in order to reproduce phenomenology: an effective nucleon mass between 0.7–0.8 MN and a compression modulus between 200–300 MeV.
