Abstract

We consider the determination of the light-quark masses obtained from QCD sum rules. We show that small-size instantons contribute sizeable corrections to these sum rules. It therefore seems impossible to provide an accurate determination of the light-quark masses in the QCD sum rules framework. © 1993.
