标题： Update on non-unitary mixing in the recent NO$ν$A and T2K data

摘要： 在这封信中，我们采用了一种非幺正混合方案来缓解 NO$\nu$A 和 T2K 数据之间的张力。 结果表明，NO$\nu$A 和 T2K 的结果可以通过由 $\alpha_{00}$ 和 $\alpha_{10}$ 引起的非幺正混合效应来解释。 For $\alpha_{00}$ there is a large overlap between the allowed NO$\nu$A and T2K regions for NH on the $\sin^2\theta_{23}-\delta_{\rm CP}$ plane at $1\,\sigma$. However, the tension still exists. NO$\nu$A rules out unitary mixing at a $3\,\sigma$ level, whereas T2K strongly prefers unitary mixing. 对于$\alpha_{10}$，张力可以通过最佳拟合点来表示，对于 NH，在两种实验中分别为$|\alpha_{10}|=0.06$和\textbf{良好解析的}。 显示英文摘要

摘要： In this letter, we have used a non-unitary mixing scheme to resolve the tension between NO$\nu$A and T2K data. It is demonstrated that the results of NO$\nu$A and T2K can be explained by the effects by non-unitary mixing arising from $\alpha_{00}$ and $\alpha_{10}$. For $\alpha_{00}$ there is a large overlap between the allowed NO$\nu$A and T2K regions for NH on the $\sin^2\theta_{23}-\delta_{\rm CP}$ plane at $1\,\sigma$. However, the tension still exists. NO$\nu$A rules out unitary mixing at a $3\,\sigma$ level, whereas T2K strongly prefers unitary mixing. For $\alpha_{10}$, the tension can be \textbf{well resolved} with the best-fit point for NH at $|\alpha_{10}|=0.06$ for both experiments.
