Description
Limits on the size of quenched chiral logs in the pion mass for Wilson fermions are investigated. The smallness of chiral logs is shown to be a result of the suppression of the hairpin diagram for small p2, such that the value of the hairpin on the pion mass shell is much smaller than the physical m2η'. A direct calculation of the topological susceptibility from the same data gives mη'∼1 GeV. (orig.)
