title = "Search for neutron decay into an antineutrino and a neutral kaon in 0.401 megaton-years exposure of Super-Kamiokande",
abstract = "We searched for bound neutron decay via n → {\=ν} + K0 predicted by the grand unified theories in 0.401 Mton · years exposure of all pure water phases in the Super-Kamiokande detector. About 4.4 times more data than in the previous search have been analyzed by a new method including a spectrum fit to kaon invariant mass distributions. No significant data excess has been observed in the signal regions. As a result of this analysis, we set a lower limit of 7.8 × 1032 years on the neutron lifetime at a 90\% confidence level.",
