本文报道了第一次测量使用NOvA探测器的$ν_μ$消失在一个$ν_μ$光束。该分析使用来自Fermilab NuMI束的靶上$2.74 \times 10^{20}$质子的14千吨当量曝光。假设正常的中微子质量等级，我们测量$Δm^{2}_{32}=(2.52^{+0.20}_{-0.18})\times 10^{-3}$ eV $^{2}$和$\sin^2θ_{23}$在0.38-0.65的范围内，都在68%的置信水平，两个垂直简并的最佳拟合点在$\sin^2θ_{23} = $ 0.43和0.60。倒置的质量层次结构的结果也。
英文摘要：
This paper reports the first measurement using the NOvA detectors of $ν_μ$ disappearance in a $ν_μ$ beam. The analysis uses a 14 kton-equivalent exposure of $2.74 \times 10^{20}$ protons-on-target from the Fermilab NuMI beam. Assuming the normal neutrino mass hierarchy, we measure $Δm^{2}_{32}=(2.52^{+0.20}_{-0.18})\times 10^{-3}$ eV$^{2}$ and $\sin^2θ_{23}$ in the range 0.38-0.65, both at the 68% confidence level, with two statistically-degenerate best fit points at $\sin^2θ_{23} = $ 0.43 and 0.60. Results for the inverted mass hierarchy are also presented.

NuMI离轴现象（英语：NuMI Off-Axis v Appearance，缩写：NOvA）实验是一个长基线中微子振荡实验，使用的是费米实验室的NuMI光束线产生的中微子源。该实验将使用两个功能相同的塑料液体闪烁体填充探测器研究μ子中微子到电子中微子的振荡，该探测器放置在离轴14毫弧度的NuMI光束上。带电中微子相互作用将被用来观察中微子味从识别的最终状态轻子。μ子带电粒子径迹的重建在探测器对准和校准的短期目标以及通过识别μ子带电电流事件的长期振荡分析中起着重要作用。提出了一种基于卡尔曼滤波的μ子径迹识别和径迹拟合的初步方法。

Constraints on Oscillation Parameters from $ν_e$ Appearance and $ν_μ$ Disappearance in NOvA
结果报告从改进的测量$ν_μ\rightarrow ν_e$转换的NOvA实验。使用与$6.05\times10^{20}$质子靶向等效的暴露，观察到33个$ν_e$候选物，背景为$8.2\pm0.8$（系统）。结合最新的NOvA $ν_μ$消失数据和来自$\sin^22θ_{13}$反应堆实验的外部约束，在大于$93\%$ C. L.时，$θ_{23}$在低八分圆中的倒置质量等级假设是不利的。对于$δ_{CP}$的所有值。
