摘要：The Kugo-Ojima confinement criterion is verified in the unquenched Landau gauge QCD simulation.
The valence quark propagator of the Kogut-Susskind fermion with use of the fermion action
including the Naik term and the staple contribution is calculated on MILC Asqtad unquenched
gauge configurations, and it shows clear evidence of infrared vanishing of the quark propagator.
