我们提出了一个参数化的观察到的增强的横向电子准弹性（QE）的响应函数的核子约束在碳作为一个功能的平方的四个动量转移（Q2）的修正约束核子的磁性形状因子。这种参数化也适用于中微子散射的横截面。如果横向增强源自介子交换流（MEC），那么理论上预期纵向或轴向贡献的任何增强都很小。本文给出了“横向增强”模型（仅基于电子散射数据）对束缚在碳中的核子的νμ、$\bar{\nu}_{\mu}$微分和总QE截面的预言.横向增强的Q2依赖性的观察，以解决长期存在的差异，在QE的总截面和差分分布之间的低能量和高能量中微子实验的核目标。
We present a parametrization of the observed enhancement in the transverse electron quasielastic (QE) response function for nucleons bound in carbon as a function of the square of the four momentum transfer (Q2) in terms of a correction to the magnetic form factors of bound nucleons. The parametrization should also be applicable to the transverse cross section in neutrino scattering. If the transverse enhancement originates from meson exchange currents (MEC), then it is theoretically expected that any enhancement in the longitudinal or axial contributions is small. We present the predictions of the “Transverse Enhancement” model (which is based on electron scattering data only) for the νμ, $\bar{\nu}_{\mu}$ differential and total QE cross sections for nucleons bound in carbon. The Q2 dependence of the transverse enhancement is observed to resolve much of the long standing discrepancy in the QE total cross sections and differential distributions between low energy and high energy neutrino experiments on nuclear targets.
