Abstract

We present preliminary results on hadronic spectrum measurements by the High Energy Monte Carlo Grand Challenge (HEMCGC) collaboration. The simulation, on a 124 lattice, uses the hybrid molecular dynamics algorithm with two flavors of staggered fermions at two quark mass values and 6/g2 = 5.6. This measurement uses Wilson valence quarks at three values of the hopping parameter on a lattice that is doubled in the time direction. Our work allows a comparative study of these two types of lattice fermions at the parameters used, and provides a check on whether the continuum limit has been reached. The results exhibit the correct trends as the chiral limit is approached.
