论文摘要
我们介绍了当前的喷气生产在电子撞机能量上的半含量不弹性散射过程的系统计算。考虑到弱相互作用的贡献，这会导致违反平等的影响。我们考虑了具有旋转1的偏振目标散射的偏振电子束的一般形式。通过应用近线性膨胀，将计算在量子染色体动力学组模型中执行至扭曲3水平，在该模型中，考虑了多个gluon散射，并自动获得了量规链接。我们介绍了结构函数和自旋/方位角不对称的完整结果，该量规定不变的横向动量依赖性parton分布函数。非偏振和偏振电子束外壳对应于24个方位角不对称，其中6个出现在领先扭曲处，而其中18个在扭曲3级中贡献。此外，我们还计算出源自电磁和弱相互作用的干扰而产生的平等侵略不对称。
We present a systematic calculation of the current jet production semi-inclusive deeply inelastic scattering process at the Electron-Ion Collider energy. Contributions from weak interactions are considered which give rise to parity violating effects. We consider the general form of the polarized electron beam scattering off the polarized target which has spin 1. The calculations are carried out up to twist-3 level in the quantum chromodynamics parton model by applying the collinear expansion where multiple gluon scattering is taken into account and gauge links are obtained automatically. We present complete results for structure functions and spin/azimuthal asymmetries in terms of the gauge invariant transverse momentum dependent parton distribution functions. Both the unpolarized and the polarized electron beam cases correspond to 24 azimuthal asymmetries, in which 6 of them appear at the leading twist, while 18 of them contribute at twist-3 level. In addition we also calculate the parity-violating asymmetries which arise from the interference of the electromagnetic and weak interactions.
