Higher Dimension Operators and Chiral Symmetry Breaking in Nambu-Jona-Lasinio Model

Abstract

We point out that adding higher dimension operators to the Nambu-Jona-Lasinio model can stabilize chiral symmetry breaking and resolve the issue raised by Kleinert and Van den Bossche that chiral symmetry breaking cannot occur for $N_c\le N_c^{\mathrm{cr}}$ due to large quantum fluctuations of the composite fields.
