摘要：

The quark propagator is at the core of lattice hadron spectrum calculations as well as studies in other non-perturbative schemes. We investigate the quark propagator with an improved staggered action (Asqtad) and an improved gluon action, which provides good quality data down to small quark masses. This is used to construct ansatze suitable for model hadron calculations as well as adding to our intuitive understanding of QCD.
