在NOVA NEAR探测器中，利用Numi束中的质子对靶，测量了包含电子的中微子电荷电流截面。GeV电子中微子相互作用的样本是迄今为止被分析的最大的样本，并且受到系统而不是统计不确定性的限制。首次给出了电子末态能量和角度的双微分截面，以及该范围内电子能量与四动量平方转移和能量的单微分依赖关系。与Genie、GiBUU、Neut和NuWro中微子事件产生器的预测作了详细的比较。在测量的所有三个横截面上，数据并不强烈倾向于一个模型而不是其他模型，尽管一些模型在单个差异横截面与其他模型之间的一致性特别好或很差。
The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector usingprotons-on-target in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited bysystematic rather than thestatistical uncertainties. The double-differential cross section in final-state electron energy and angle is presented for the first time, together with the single-differential dependence on(squared four-momentum transfer) and energy, in the range. Detailed comparisons are made to the predictions of the GENIE, GiBUU, NEUT, and NuWro neutrino event generators. The data do not strongly favor a model over the others consistently across all three cross sections measured, though some models have especially good or poor agreement in the single differential cross section vs.
