Query: Delocalized Operator Expansion   A generalization of Wilson's local OPE for the short-distance expansion of
Euclidean current correlators, called delocalized operator expansion (DOE),
which has been proposed recently, is discussed. The DOE has better convergence
properties than the OPE and can account for non-local non-perturbative QCD
effects.
