论文摘要
（抗）中微子核散射在探测辐射结构以及电牵引现象方面起着非常重要的作用。为此，我们计算了喷气产量半含有深度非弹性（抗）中微子核散射过程。假定初始（抗）中微子被带有自旋1的目标粒子散射。由于分解定理的限制，计算是在量子染色体动力学parton模型框架中进行的，直至树级别扭曲3。我们考虑中性电流和带电的电流过程，并由于相似的相互作用形式将其写入统一形式。考虑到横截面的角度调制和极化，我们计算了完整的方位角不对称。我们还计算了固有的不对称性，这些不对称揭示了夸克内在横向动量的分布的不平衡。我们发现这些不对称性可以用横向动量依赖性的Parton分布函数（TMD PDF）和电动耦合表示。使用确定的耦合，这些不对称性可用于提取TMD PDF，并进一步研究HADRONIC结构。
The (anti)neutrino nucleus scattering plays a very important role in probing the hadronic structure as well as the electroweak phenomenologies. To this end, we calculate the jet production semi-inclusive deeply inelastic (anti)neutrino nucleus scattering process. The initial (anti)neutrino is assumed to be scattered off by a target particle with spin 1. Due to the limitation of the factorization theorem, calculations are carried out in the quantum chromodynamics parton model framework up to tree level twist-3. We consider both the neutral current and the charged current processes and write them into a unified form due to the similar interaction forms. Considering the angular modulations and polarizations of the cross section, we calculate the complete azimuthal asymmetries. We also calculate the intrinsic asymmetries which reveal the imbalance in the distribution of the intrinsic transverse momentum of the quark. We find that these asymmetries can be expressed in terms of the transverse momentum-dependent parton distribution functions (TMD PDFs) and the electroweak couplings. With the determined couplings, these asymmetries can be used to extract the TMD PDFs and further to study the hadronic structures.
