Abstract

We present results of a search for proton decays, p → ν̄K+, using data from a 33 kt · yr exposure of the Super-Kamiokande detector. Two decay modes of the kaon, K+ → μ+νμ and K+ → π+π0, were studied. The data were consistent with the background expected from atmospheric neutrinos; therefore a lower limit on the partial lifetime of the proton τ/B(p → ν̄K+) was found to be 6.7 × 1032 years at 90% confidence level.
