Light Hadron Masses in QCD with Valence Wilson Quarks at beta=6.25 from a Parallel PC Cluster
Abstract
We present results for π, and proton and masses from our recently built Pentium cluster. The previous results for quenched Wilson fermions by MILC and GF11 collaborations are compared at β=6/g2=5.7 and 5.85 with the same parameters on the 83×32 lattice. New data are shown at β=6.25 on the 123×36 and 163×32 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.
