Abstract

We searched for proton decay via pμ+K0 in 0.37Mton·years of data collected between 1996 and 2018 from the Super-Kamiokande water Cherenkov experiment. The selection criteria were defined separately for KS0 and KL0 channels. No significant event excess has been observed. As a result of this analysis, which extends the previous search by an additional 0.2Mton·years of exposure and uses an improved event reconstruction, we set a lower limit of 3.6×1033years on the proton lifetime.
