Current and constituent quark masses: Beyond chiral-symmetry breaking

Abstract
It is shown how the current quark mass, engendered by the electroweak sector, gives rise to a constituent quark mass, via the Dyson-Schwinger equations. The chiral-symmetry-breaking phenomenon of massless QCD is thereby seen to have an implementable generalization to the situation in which the strong bare mass is nonzero. A consistent renormalization is carried out for an arbitrary covariant gauge.
