Abstract:
A cutting rule for the correlation functions of higher twist amplitudes,which is proposed on the naive parton level by Jaffe,is justified for its valid when considering QCD corrections. Using the collinear time ordered perturbation theory,we show that this cutting rule is held at any orders of ans(μ2) provided all initial parton operators are separable on the light-cone direction y-.
