论文摘要
核结构功能中的核培养基效应和核靶中微子的深度非弹性散射（DIS）的差分横截面在核靶中的中微子中进行了研究，包括$ x $的区域，包括$ x $ x \ ge 1 $。使用在微观场理论模型中计算的核子光谱函数，包括核子运动和核子相关性的结合能引起的核培养基效应。使用Martin-Motylinski-Harland Lang-Thorne（MMHT）在近代到接头的领先顺序（NNLO）上评估核结构函数和横截面的数值结果，并获得了核酸分配功能（PDF）的核心分布功能（PDF）和j JOL的分散型（PDF），并与DATA（PDF）进行了比较（PDF）。核物理设施（NPA）。在中微子散射的情况下，结果与理解通过主要注射器中微子实验测量的最新包含横截面的贡献有关，以研究V-A相互作用（Minerva）以及理论预测，用于深层地下中微子实验（Dune）。还讨论了等核校正在较重的核能中的重要性以及运动学切割对CM Energy $ W $定义DIS区域的影响。
The nuclear medium effects in the nuclear structure functions and differential cross sections in the deep inelastic scattering (DIS) of charged lepton and neutrino from nuclear targets are studied in the region of large $x$ including $x\ge 1$. The nuclear medium effects due to the Fermi motion and the binding energy of nucleons and the nucleon correlations are included using nucleon spectral function calculated in a microscopic field theoretical model. The numerical results for the nuclear structure functions and the cross sections are obtained using the nucleon structure function evaluated at the next-to-next-to-leading order (NNLO) with the Martin-Motylinski-Harland Lang-Thorne (MMHT) parameterization of the nucleonic parton distribution functions (PDFs) and are compared with the available experimental data on electron scattering from the Jefferson Lab (JLab) and SLAC Nuclear Physics Facility (NPAS). In the case of neutrino scattering the results are relevant for understanding the DIS contributions to the recent inclusive cross sections measured by the Main Injector Neutrino ExpeRiment to study v-A interactions (MINERvA) as well as theoretical predictions are made for Deep Underground Neutrino Experiment (DUNE). The importance of isoscalarity corrections in heavier nuclear targets as well as the effect of the kinematic cut on the CM energy $W$ in defining the DIS region have also been discussed.
