We compare the static nucleon properties in the perturbative (chiral perturbation theory) and the non-perturbative model. We consider a chiral model for the nucleon based on the linear sigma model with scalar-isoscalar scalar-isovector mesons coupled to quarks, and solved it using the coherent pair approximation.
