Facets of confinement and dynamical chiral symmetry breaking.
The gap equation is a cornerstone in understanding dynamical chiral symmetry breaking and may also provide clues to confinement. A symmetry-preserving truncation of its kernel enables proofs of important results and the development of an efficacious phenomenology. We describe a model of the kernel that yields: a momentum-dependent dressed-quark propagator in fair agreement with quenched lattice-QCD results; and chiral limit values, f{sup 0}{sub pi} = 68 MeV and {l_angle} {bar q} q {r_angle} = -(190 MeV){sup 3}. It is compared with models inferred from studies of the gauge sector.
