We have searched for proton decay via p→e+π0 using data from a 25.5kton˙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 1.6×1033years at a 90% confidence level.Received 19 May 1998DOI:https://doi.org/10.1103/PhysRevLett.81.3319©1998 American Physical Society
