Abstract:
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.
