Abstract

The international accelerator neutrino experiment T2K (Tokai-to-Kamioka) began accumulating data in 2010 and has since then accomplished 10 runs in the neutrino and antineutrino modes. The present article reports on the latest results following from the analysis of these data and including the first ever 3\(\sigma\) constraints on the CP-violating phase \(\delta_{CP}\). Also, the plans for an upgrade of the near detector ND280 are surveyed.

T2K实验：最新结果和前景

摘要

国际加速器中微子实验T2K（Tokai-to-Kamioka）于2010年开始积累数据，此后已在中微子和反中微子模式下完成了10次运行。本文根据对这些数据的分析报告了最新结果，包括对违反CP的阶段\（\ delta_ {CP} \）的第三个\（\ sigma \）约束。此外，还对升级近距离探测器ND280的计划进行了调查。
