  "abstract": "A search for proton decay via $p\\rightarrow l^{+}+X$, where $l^{+}$ is a positively charged lepton and $X$ is an invisible, massless, neutral particle, was performed using a 401~kton$\\cdot$years exposure representing the entire pure water phase of Super-Kamiokande. No significant indication of a proton decay was observed beyond the expected atmospheric neutrino background. Lower limits on the partial lifetime of the proton were set to at $1.72\\times10^{33}$ years for $p\\rightarrow e^{+}+X$ and $0.61\\times10^{33}$ years for $p\\rightarrow μ^{+}+X$ at the $90\\%$ confidence level. These results improve on previous limits by factors of 2 and 1.5, respectively.",
