Current mass dependence of the quark condensate and the constituent quark mass

Abstract

We discuss the current mass dependence of the basic quantities of the quark models -- constituent quark mass M and quark condensate i<psi^dagger psi >. The framework of the consideration is QCD instanton vacuum model.
