Abstract

A general procedure is introduced allowing for the complete, infinite twist decomposition of non-local vector operators in QCD off the light-cone. The method is applied to the operators ψ(x) γμψ(-x) and ψ(x) σμν xνψ(-x) as well as to their matrix elements thereby determining all power (resp. target mass) corrections being relevant for the related distribution amplitudes.
