Quenched lattice QCD studies using WilsonDirac fermions have encountered large statistical errors in calculations involving very light quarks. A small subset of the gauge configurations seem to play a dominant role in the final results. These “exceptional configurations” have limited studies to quark masses much larger than the up and down quark masses. The… (More)
