我们通过1996年至2018年从Super-Kamiokande水切伦科夫实验中收集的数据搜索质子衰变。选择标准分别为和渠道定义。未观察到显著事件过量。由于这种分析，它扩展了以前的搜索额外的曝光，并使用改进的事件重建，我们设置了一个质子寿命的下限。
We searched for proton decay viainof data collected between 1996 and 2018 from the Super-Kamiokande water Cherenkov experiment. The selection criteria were defined separately forandchannels. No significant event excess has been observed. As a result of this analysis, which extends the previous search by an additionalof exposure and uses an improved event reconstruction, we set a lower limit ofon the proton lifetime.
