Saturation Properties of Nuclear Matter with a Nonlocal Confining Solitons

Abstract

We examine saturation properties of a quark-based picture of nuclear matter. Soliton matter consisting of nonlocal confining solitons is used to model nuclear matter. Each composite nucleon is described by a non-topological soliton as given by the Global Color Model. We apply techniques and concepts from the discription of crystal lattices. In particular, the Wigner-Seitz approximation is used to calculate the properties of the soliton lattice at the mean-field level. We focus on infinite nuclear matter at around standard nuclear matter density with the simplest one-parameter assumption for the gluon propagator. the saturation density and incompressibility are calculated as functions of the single parameter of the model
