Consistent Results for Quenched Chiral Logarithms

Abstract: The results of a study of chiral log effects in quenched QCD are presented. Using the modified quenched approximation to resolve the exceptional configuration problem, accurate results are obtained for pion masses as low as 190 MeV. A comparison is made between chiral log effects in the pion mass, the pseudoscalar and axial vector decay constants, and measurements of the $\eta'$ hairpin and topological susceptibility.
