Toy model of the repulsive core of the nucleon-nucleon potential

We study the simplest quark model assuming that the sea of gluons and quark-antiquark pairs can be treated as a part of a static force and proceeding to calculate the hadronic states by solving the Schrödinger equation for a static confining interaction. We refer to this model, starting from a system of six interacting constituent quarks, and examine how the picture of two structureless nucleons can change when the effects caused by the substructure of the nucleons are taken into account.
