What is Chiral Effects of Quenched η′ Loops about?

Preliminary results of a study of quenched chiral logarithms at /~ = 5.7 are presented. Four independent determinations of the quenched chiral log parameter 5 are obtained. Two of these are from estimates of the ~' mass, one from the residue of the hairpin diagram and the other from the topological susceptibility combined with the Witten-Veneziano formula. The other two determinations of 5 are from measurement of virtual ~/' loop 2 effects in m~ vs. quark mass and in the chiral behavior of the pseudoscalar decay constant. All of our results are consistent with ~ = .080(15). The expected absence of quenched chiral logs in the axial-vector decay constant is also observed.
