[...] We present an unquenched calculation of the quark propagator in Landau gauge with 2� 1 flavors of dynamical quarks. We use configurations generated with an improved staggered (‘‘Asqtad’’) action by the MILC Collaboration. This quark action has been seen to have excellent rotational symmetry and scaling properties in the quenched quark propagator. Quenched and dynamical calculations are performed on a 20 3 � 64 lattice with a nominal lattice spacing of a � 0:125 fm. The matched quenched and dynamical lattices allow us to investigate the relatively subtle sea-quark effects, and even in the quenched case the physical volume of these lattices gives access to lower momenta than our previous study. We calculate the quark mass function and renormalization function for a variety of valence and sea-quark masses.
