Zusammenfassung
We reexamine the scale dependence of the Efremov-Teryaev-Qiu-Sterman twist-3 matrix element that has been studied already by the four different groups with conflicting results [Z.-B. Kang and J.-W. Qiu, Phys. Rev. D 79, 016003 (2009); J. Zhou, F. Yuan, and Z.-T. Liang, Phys. Rev. D 79, 114022 (2009); W. Vogelsang and F. Yuan, Phys. Rev. D 79, 094010 (2009); and V. M. Braun, A.N.

Qiu, Phys. Rev. D 79, 016003 (2009); J. Zhou, F. Yuan, and Z.-T. Liang, Phys. Rev. D 79, 114022 (2009); W. Vogelsang and F. Yuan, Phys. Rev. D 79, 094010 (2009); and V. M. Braun, A.N. Manashov, and B. Pirnay, Phys. Rev. D 80, 114002 (2009)]. We find that we can in fact reproduce the results of V. M. Braun, A.N. Manashov, and B. Pirnay, Phys. Rev. D 80, 114002 (2009) with the methods of J. Zhou, F. Yuan, and Z.-T. Liang, Phys. Rev. D 79, 114022 (2009) when we treat some subtleties with greater care, thus easing the mentioned conflict.
