QCD sum rules are useful tools for studying the spectral properties of hadrons; however, assumptions underlying standard sum-rule analyses can lead to inconsistencies with known results of chiral perturbation theory. This possibility is demonstrated with QCD sum-rule extractions of the nucleon mass ...
Direct instanton contributions to the "Rq sum rule in the instanton liquid model [5] are scaled by the parameter pc, and can be excised simply by going to the p,. ~ oc limit. It should be noted that a sum-rule analysis containing both the rather large two-loop perturbative term and...
