摘要
T2K 实验报告了利用出现和消失通道的中微子与反中微子振荡的更新测量。该结果来自中微子（反中微子）模式下 个打靶质子的曝光。中微子相互作用模型和远探测器重建已得到显著改进。还执行了广泛的模拟数据研究，以量化相互作用模型不确定性对 T2K 振荡参数灵敏度的影响。T2K 执行了多个振荡分析，给出了 PMNS 参数的频率学派和贝叶斯区间。对于包含来自反应堆数据的 \ssqthonethree 约束并假设正常质量排序的拟合，T2K 测量得到 和 eVc。贝叶斯分析显示出对正常质量排序的弱偏好（89% 后验概率）和上 象限（80% 后验概率），两种情况下均假设均匀先验概率。T2K 数据在 水平上排除了中微子振荡中的 CP 守恒。
