    Abstract:
    We have searched for proton decay via p → e+ π0 using data from a 25.5 kton · yr exposure of the Super-Kamiokande detector. We find no candidate events with an expected background induced by atmospheric neutrinos of 0.1 events. From these data, we set a lower limit on the partial lifetime of the proton τ/Bp→e+π0 to be 1.6 × 1033 years at a 90% confidence level.
