Abstract

We have searched for proton decays via p -> e(+)pi(0) and p ->mu(+)pi(0) using data from a 91.7 kt center dot yr exposure of Super-Kamiokande-I and a 49.2 kt center dot yr exposure of Super-Kamiokande-II. No candidate events were observed with expected backgrounds induced by atmospheric neutrinos of 0.3 events for each decay mode. From these results, we set lower limits on the partial lifetime of 8.2x10(33) and 6.6x10(33) years at 90 confidence level for p -> e(+)pi(0) and p ->mu(+)pi(0) modes, respectively.

No candidate events were observed with expected backgrounds induced by atmospheric neutrinos of 0.3 events for each decay mode. From these results, we set lower limits on the partial lifetime of 8.2x10(33) and 6.6x10(33) years at 90 confidence level for p -> e(+)pi(0) and p ->mu(+)pi(0) modes, respectively.
