Abstract
The hybrid soliton model describes nucleons as consisting of quarks and pion and sigma meson fields. We place these nucleons on a three-dimensional lattice and calculate the dependence of the total energy on the density. Various higher order terms in the meson fields are implemented into the Lagrangian of the model to change the behavior of the interaction energy between the nucleons. Because of the increase in quark kinetic energy at higher densities, we have not been able to obtain a minimum at ground state nuclear density.
