Abstract
An improved ''Feynman rule'' approach is presented for evaluating quar k- and gluon-condensate contributions to correlation functions to all orders in the quark mass parameter m. Although plane-wave and coordina te-space approaches are known to yield differing expressions for the s luon-condensate contributions to the quark propagator, the heavy-quark expansion relationship between gluon and heavy-quark condensates is s hown to be insensitive to these differences.
