Workshop on Computational Hadron Physics (2005.Nicosia, Chipre)We summarise recent results on the properties of gluons, quarks and light mesons from the Green's functions approach to QCD. We discuss a self-consistent, infrared power law solution for the Schwinger-Dyson equations of the 1PI Greens functions of Yang-Mills theory. The corresponding running coupling has a universal fixed point at zero momentum. Based on these analytical results a truncation scheme for the coupled system of Schwinger-Dyson equations for the propagators of QCD and the Bethe-Salpeter equation for light mesons has been formulated. We compare numerical results for charge eigenstate vector and pseudoscalar meson observables with corresponding lattice data. The effects of unquenching the system are found to be small but not negligible.engjournal articlehttp://dx.doi.org/10.1016/j.nuclphysbps.2006.01.011http://arxiv.org/abs/hep-ph/0511147http://www.sciencedirect.comopen access53Yang-Mills TheoryLandau GaugeConfinementExponentsPhysicsVertexFísica (Física)22 Física
