Resum

An improved "Feynman rule" approach is presented for evaluating quark- and gluon-condensate contributions to correlation functions to all orders in the quark mass parameter m. Although plane-wave and coordinate-space approaches are known to yield differing expressions for the gluon-condensate contributions to the quark propagator, the heavy-quark expansion relationship between gluon and heavy-quark condensates is shown to be insensitive to these differences. © 1993.
