Abstract

We show that the dynamical quark mass in effective nonlocal models can vanish at zero virtuality of the quark as M(p²)\ensuremath∝p². Our arguments follow from the constrained-instanton model of the QCD vacuum and from QCD sum rule calculations with nonlocal condensates. The discussed models also lead to analyticity of M(p²) in the vicinity of zero.
