在本文中，我们提出了第一次测量的专属电子中微子截面的MicroBooNE实验使用的数据从助推器中微子束线在费米实验室。这些测量是对一组没有末态π介子的带电电子中微子进行的。微分截面提取的能量和角度相对于电子和领先的质子束。作为质子能量的函数的微分截面测量使用的事件与质子以上和以下的能见度阈值。这是通过包括一个单独的选择电子中微子事件没有重建的质子候选人除了那些质子候选人。结果进行了比较，从几个现代发电机的预测，我们发现这些模型的数据吻合得很好。数据显示，与预测较低总横截面的发生器（如GENIE v3和NuWro）的最佳一致性（由-值量化）。
In this paper we present the first measurements of an exclusive electron neutrino cross section with the MicroBooNE experiment using data from the Booster neutrino beamline at Fermilab. These measurements are made for a selection of charged-current electron neutrinos without final-state pions. Differential cross sections are extracted in energy and angle with respect to the beam for the electron and the leading proton. The differential cross section as a function of proton energy is measured using events with protons both above and below the visibility threshold. This is done by including a separate selection of electron neutrino events without reconstructed proton candidates in addition to those with proton candidates. Results are compared to the predictions from several modern generators, and we find the data agrees well with these models. The data shows best agreement, as quantified by the-value, with the generators that predict a lower overall cross section, such as GENIE v3 and NuWro.
