论文摘要
本文提出了对MK模型的更新，该模型的开发是为了描述中微子 - 核子相互作用中的单胎产生。最初，MK模型使用了螺旋幅度和rine和sehgal模型的Hadronic电流形式因子。该更新包括第一个和第二共振区域中的螺旋性振幅的新定义，以及新的向量电流形式。拟合电子 - 普罗顿散射数据用于确定这些矢量电流形式因素，并将误差分配给模型的约束自由参数。
This paper presents an update to the MK model, which was developed to describe single pion production in neutrino-nucleon interactions. Originally the MK model used the helicity amplitudes and the hadronic current form-factors of the Rein and Sehgal model. The update includes a new definition for the helicity amplitudes in the first and second resonance regions, and new vector-current form factors. Fits to electron-proton scattering data were used to determine these vector-current form factors, and to assign errors to the constrained free parameters of the model.
