Light Hadron Masses in QCD with Valence Wilson Quarks at beta=6.25 from a Parallel PC Cluster
We present results for $π$, $ρ$ and proton and $Δ$ masses from our recently built Pentium cluster. The previous results for quenched Wilson fermions by MILC and GF11 collaborations are compared at $β=6/g^2$=5.7 and 5.85 with the same parameters on the $8^3\times32$ lattice. New data are shown at $β$=6.25 on the $12^3\times36$ and $16^3\times32$ lattices. Such a larger $β$ value is useful for extrapolating the lattice results to the continuum limit. The smearing technique is systematically investigated and shown to greatly improve the spectrum data.
