摘要：

T2 K合作将$ν_μ$消失和$ν_e $出现数据结合在三味中微子振荡分析中。马尔可夫链蒙特卡罗的结果估计的振荡参数和一维68%贝叶斯可信区间在$δ_{CP} = 0$如下：$\sin^{2}θ_{23} = 0.520^{+0.045}_{-0.050}$，$\sin^{2}θ_{13} = 0.0454^{+ 0.011}_{-0.014}$和$|Δm^{2}_{32}| = 2.57\pm0.11$，与点的最高后验概率的倒置层次。最近的测量$θ_{13}$从反应堆中微子实验相结合的T2 K数据产生以下估计：$\sin^{2}θ_{23} = 0.528^{+0.055}_{-0.038}$，$\sin^{2}θ_{13} = 0.0250 \pm 0.0026$和$|Δm^{2}_{32}| = 2.51\pm0.11$，与正常层次中的最高后验概率点。此外，数据排除了在0.14 $π$-0.87 $π$之间的$δ_{CP}$值，概率为90%。

英文摘要：

The T2K collaboration has combined the $ν_μ$ disappearance and $ν_e $appearance data in a three-flavor neutrino oscillation analysis. A Markov chain Monte Carlo results in estimates of the oscillation parameters and 1D 68% Bayesian credible intervals at $δ_{CP} = 0$ as follows: $\sin^{2}θ_{23} = 0.520^{+0.045}_{-0.050}$, $\sin^{2}θ_{13} = 0.0454^{+ 0.011}_{-0.014}$ and $|Δm^{2}_{32}| = 2.57\pm0.11$, with the point of highest posterior probability in the inverted hierarchy. Recent measurements of $θ_{13}$ from reactor neutrino experiments are combined with the T2K data resulting in the following estimates: $\sin^{2}θ_{23} = 0.528^{+0.055}_{-0.038}$, $\sin^{2}θ_{13} = 0.0250 \pm 0.0026$ and $|Δm^{2}_{32}| = 2.51\pm0.11$, with the point of highest posterior probability in the normal hierarchy. Furthermore, the data exclude values of $δ_{CP}$ between 0.14$π$-0.87$π$ with 90% probability.
