The massless linear sigma model with loop corrections. (English) Zbl 1149.81336
Summary: We study the effect of one-loop corrections from nucleon together with those from meson in the massless linear sigma model, where we perform the Coleman-Weinberg (CW) renormalization procedure in order to obtain the stable effective potential. We also study the non-perturbative and higher loop corrections with fermions and bosons in the Cornwall, Jackiw and Tomboulis (CJT) method.
