摘要

Equation?(19) of Phys. Rev. D 67 , 094003 (2003) turns out to contain mistakes, as pointed out recently in Phys. Rev. D 97 , 074019 (2018) by H.?H. Matevosyan et?al. In particular, Eq.?(19) contains an erroneous explicit dependence on the angle ? l , and the terms linear in g ^ have an opposite sign with respect to what one would deduce from Fig.?1. As a result, the expressions for the projection of the cos ( 2 ( ? R ? ? R ˉ ) ) azimuthal dependence are incorrect. Specifically, Eqs.?(34), (37), and (38) should all vanish, which means that the cos ( 2 ( ? R ? ? R ˉ ) ) projection is not a measure of the di-hadron fragmentation function G 1 ⊥ , as concluded in the paper. The vanishing of the projection explains the nonobservation of the related asymmetry in the recent experimental search by the BELLE Collaboration (A. Abdesselam et?al. , arXiv:1505.08020). We refer to Phys. Rev. D 97 , 074019 (2018) for the correct version of Eq.?(19) and for an alternative nonzero projection of the asymmetry that does probe the function G 1 ⊥ .

Abdesselam et al。,arXiv:1505.08020)进行的实验搜索未观察到相关的不对称性。我们指的是物理。修订版D 97,074019(2018)适用于等式(19)的正确版本,以及用于探查函数G 1 projection的非对称性的另一个非零投影。
