Abstract

We present preliminary results from the 1991 HEMCGC simulations with staggered dynamical fermions on a 163×32 lattice at β = 5.6 with sea quark masses amq = 0.025 and 0.01. The spectroscopy was done both for staggered valence quarks with mass equal to the sea quark masses and for Wilson valence quarks at six different values for κ, 0.1320, 0.1410, 0.1525, 0.1565, 0.1585, and 0.1600. In addition to the measurements performed in our earlier work we also measured the Δ and other 'extended' hadrons for staggered valence quarks and pseudo-scalar decay constants and vector meson matrix elements, the wave function at the origin, for Wilson valence quarks.
