论文摘要
我们检查了最近更新的中微子振荡数据 - 特别是从Tokai到Kamioka和Numi Off-Axis $ν_e$外观实验 - 以及如何分析它们以确定中微子质量订购是正常的（$ m_1 <m_2 <m_2 <m_3 $）还是倒置（$ m_3 <m_3 <m_3 <m_1 <m_1 <m_1 <m_2 $）。我们表明，尽管以前的结果对正常订购具有很强的偏爱，但使用T2K和NOVA的最新数据，这种偏好几乎消失了。此外，我们强调了该结果对于中微子的非振荡探针的重要性，包括中微子双β衰变和宇宙学。包括Juno，Dune和T2HK在内的未来实验将提供有价值的信息，并在较高的置信度下确定质量订购。
We inspect recently updated neutrino oscillation data -- specifically coming from the Tokai to Kamioka and NuMI Off-axis $ν_e$ Appearance experiments -- and how they are analyzed to determine whether the neutrino mass ordering is normal ($m_1 < m_2 < m_3$) or inverted ($m_3 < m_1 < m_2$). We show that, despite previous results giving a strong preference for the normal ordering, with the newest data from T2K and NOvA, this preference has all but vanished. Additionally, we highlight the importance of this result for non-oscillation probes of neutrinos, including neutrinoless double beta decay and cosmology. Future experiments, including JUNO, DUNE, and T2HK will provide valuable information and determine the mass ordering at a high confidence level.
