论文摘要
通过明确的示例,我们表明,Twist-4 Parton发行量没有Parton的解释,因为强子内的Parton或Partons可以携带$ x> 1 $> 1 $或$ x <-1 $的势头分数$ x $。共线性事实化的研究的Twist-4 Parton分布对于$ \ vert x \ vert> 1 $具有力量。相应的横向动量依赖性parton分布也没有Parton解释。他们是有限的。讨论了我们的结果的含义。
Through explicit examples we show that twist-4 parton distributions have no parton interpretation in the sense that parton or partons inside a hadron can carry the momentum fraction $x$ of the hadron with $x >1$ or $x<-1$. The studied twist-4 parton distributions of collinear factoization are power-divergent for $\vert x\vert >1$. The corresponding transverse momentum dependent parton distributions have also no parton interpretation. They are finite. The implications of our results are discussed.
