我们重新检查了 ETQS（Efremov-Teryaev-Qiu-Sterman）twist-3 矩阵元的尺度依赖性，该矩阵元已由四个不同的小组研究过，结果相互矛盾参考文献[1-4]。我们发现我们实际上可以重现参考文献[4]的结果方法参考文献[4]当我们更加谨慎地对待一些微妙之处时，就会缓解上述冲突。
We reexamine the scale dependence of the ETQS (Efremov-Teryaev-Qiu-Sterman) twist-3 matrix element which has been studied already by the four different groups with conflicting results Ref.[1-4]. We find that we can in fact reproduce the results of Ref.[4] with the method Ref.[4] when we treat some subtleties with greater care, thus easing the mentioned conflict.
