Complete twist-decomposition for non-local QCD vector operators in x-space
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 (x) γμ (-x) and (x) σμ x (-x) as well as to their matrix elements thereby determining all power (resp. target mass) corrections being relevant for the related distribution amplitudes.
