论文摘要
我们使用Nova Long-Baseline实验的最新三种中微子振荡产生，使用$ν_μ\ toν_μ$，$ \barν_μ\ to \barν_μ$，$ \barν_μ$，$ \barν_μ\，$ν_μ\ cogrumention and umgrument and $ \ barv to \ barv to \ barv to \ barv to \ barv $ 13.6 \ times 10^{20} $中微子束的质子 - $ 12.5 \ times 10^{20} $ protons-protons-on target of antineutrino beam。大气参数的最佳拟合值为$δm^2_ {32} =（2.41 \ pm0.07）\ times 10^{ - 3} $ ev $^2 $，$ \ sin^2θ_{23} = 0.57^{+0.57^{+0.03} （0.82^{+0.27} _ { - 0.87}）π$。振荡参数的数据违反组合在$ν_{e} $ vs $ \barν_{e} $外观之间导致较大的不对称。
We present the most recent 3-flavor neutrino oscillation results from the NOvA long-baseline experiment, using a joint fit of $ν_μ\to ν_μ$, $\barν_μ \to \barν_μ$, $ν_μ\to ν_{e}$, and $\barν_μ\to \barν_{e}$ channels, and an accumulated exposure of $13.6 \times 10^{20}$ protons-on-target of neutrino beam and $12.5 \times 10^{20}$ protons-on-target of antineutrino beam. The best-fit values for the atmospheric parameters are $Δm^2_{32} = (2.41\pm0.07)\times 10^{-3}$ eV$^2$, $\sin^2θ_{23} = 0.57^{+0.03}_{-0.04}$ and $δ_{CP} = (0.82^{+0.27}_{-0.87}) π$. The data disfavor combinations of oscillation parameters that lead to large asymmetries between the rates of $ν_{e}$ vs $\barν_{e}$ appearance.
