论文摘要
本文介绍了MK单胎生产模型\ cite {Mk，Mk2}到高强子不变质量（$ W $）和高动量转移，以符合由于Quark-Hadron双重性而引起的扰动QCD的预测。考虑到实验数据和改进的评估技术，确定了电子核子横截面中几种共振相互作用和非谐振背景的新形式。拟合电子 - 普罗替子散射数据用于计算矢量电流形式因素，并将不确定性分配给模型的约束自由参数。这项工作的HADRON电流结果可用于确定相应的中微子核子横截面中的矢量电流，这对于长期基线中微子振荡测量中的事件发生器来说是重要的输入。
This paper presents an extension of the MK single pion production model \cite{MK, MK2} to high hadron invariant mass ($W$) and high momentum transfer to conform to the predictions of perturbative QCD due to quark-hadron duality. New form factors for several resonant interactions and non-resonant background in the electron-nucleon cross-sections are determined taking into account the experimental data and improved evaluation techniques. Fits to electron-proton scattering data are used to calculate the vector-current form factors, and to assign uncertainties to the constrained free parameters of the model. The %hadron currents results from this work can be used to determine the vector current in the corresponding neutrino-nucleon cross-sections, which are an important input for event generators in long baseline neutrino oscillation measurements.
