我们报道了第一次测量氩气带电电流单次生产的通量积分截面。这项测量是用MicroBooNE探测器进行的，MicroBooNE探测器是一个85吨的活性质量液态氩时间投影室，暴露在费米实验室的助推器中微子束下。我们将氩气的结果与以往在较轻原子核上的测量结果进行了比较，以研究中微子核散射中介子产生和输运模型中使用的尺度假设。所使用的技术是利用在地球表面运行的液态氩时间投影室成功重建和分析产生电磁终态的中微子相互作用的重要证明。
We report the first measurement of the flux-integrated cross section ofcharged-current singleproduction on argon. This measurement is performed with the MicroBooNE detector, an 85 ton active mass liquid argon time projection chamber exposed to the Booster Neutrino Beam at Fermilab. This result on argon is compared to past measurements on lighter nuclei to investigate the scaling assumptions used in models of the production and transport of pions in neutrino-nucleus scattering. The techniques used are an important demonstration of the successful reconstruction and analysis of neutrino interactions producing electromagnetic final states using a liquid argon time projection chamber operating at the Earth’s surface.
