Abstract
We searched for proton decay via p→μ+K0 in 0.37 Mton⋅years of data collected between 1996 and 2018 from the Super-Kamiokande water Cherenkov experiment. The selection criteria were defined separately for
K0S and K0L channels. No significant event excess has been observed. As a result of this analysis, which extends the previous search by an additional 0.2 Mton⋅years of exposure and uses an improved event reconstruction, we set a lower limit of 3.6×1033 years on the proton lifetime.
