Abstract

We present the results of searches for nucleon decay via n→¯νπ0 and p→¯νπ+ using data from a combined 172.8 kt⋅yr exposure of Super-Kamiokande-I,-II, and-III. We set lower limits on the partial lifetime for each of these modes: τn→¯νπ0>1.1×1033 years and τp→¯νπ+>3.9×1032 years at a 90% confidence level.
