摘　　要：利用共线极限下的时序微扰理论将关联函数的切割法则推广到包含ans( μ2 )阶的微扰QCD修正 。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 a n s(μ 2) provided all initial parton operators are separable on the light-cone direction y -.
