本文报道了在平均中微子能量为的氩原子中性流相互作用中的首次测量结果。我们使用的数据从MicroBooNE探测器的85公吨的有效体积液态氩时间投影室位于费米实验室的助推器中微子束，并暴露于质子的目标进行测量。NC事件的测量报告两个排他性的事件拓扑结构不带电π介子。这些拓扑结构包括两个光子和一个质子的拓扑结构，以及两个光子和零个质子的拓扑结构。通量平均截面为每个排他性的拓扑结构，并为他们的半包容性的组合提取（效率校正为两个加质子的最终状态），并将结果进行比较，从thegenie，中性，andnuwroneutrino事件发生器的预测。我们分别测量了半包容NC、排他NC和排他NC过程的、、和截面。
We report the first measurement ofproduction in neutral current (NC) interactions on argon with average neutrino energy of. We use data from the MicroBooNE detector’s 85 metric tons active volume liquid argon time projection chamber situated in Fermilab’s Booster Neutrino Beam and exposed toprotons on target for this measurement. Measurements of NCevents are reported for two exclusive event topologies without charged pions. Those include a topology with two photons from the decay of theand one proton and a topology with two photons and zero protons. Flux-averaged cross sections for each exclusive topology and for their semi-inclusive combination are extracted (efficiency correcting for two-plus proton final states), and the results are compared to predictions from thegenie,neut, andnuwroneutrino event generators. We measure cross sections of,, andfor the semi-inclusive NC, exclusive NC, and exclusive NCprocesses, respectively.
