Abstract

We discuss some aspects of the hadron spectrum with two flavors of Kogut-Susskind dynamical quarks at 6/g² = 5.6 and am_q = 0.01 and 0.025, using both Kogut-Susskind and Wilson valence quarks. Our high statistics simulations allow us to study systematic errors. Among the problematic features of our results are a dip in the pion effective mass which we ascribe to replicating the lattice in the time direction and large finite size effects in the baryon masses. We also compare the full QCD results to a quenched simulation at similar lattice spacing and quark masses to test whether the effects of dynamical fermions can be absorbed into renormalization of the lattice parameters.
