摘要：

We construct a perfect lattice action for staggered fermions by blocking from the continuum. The locality, spectrum and pressure of such perfect staggered fermions are discussed, We also derive a consistent fixed point action for free gauge fields and discuss its locality as well as the resulting static quark-antiquark potential, This provides a basis for the construction of (classically) perfect lattice actions for QCD using staggered fermions.
