摘要
It is shown on general ground that there exist two qualitatively distinct solutions of the Dyson-Schwinger equation for the quark propagator in the case of non-zero current quark mass. One solution corresponds to the "Nambu-Goldstone" phase and the other one corresponds to the "Wigner" phase in the chiral limit.
