Popis:	We study chiral symmetry breaking using the quark gap equation supplemented with the infrared-finite gluon propagator and ghost dressing function obtained from large-volume lattice simulations. One of the most important ingredients of this analysis is the non-Abelian quark-gluon vertex, which displays a crucial dependence on the ghost dressing function and the quark-ghost scattering amplitude. The various theoretical ingredients necessary for this construction are reviewed in detail. As a result, we obtain a dynamical quark masses of the order of 300 MeV, which is used to compute phenomenological parameters such as the pion decay constant and the quark condensate.
