Abstract

We present the results of searches for nucleon decay via n→ν¯π0 and p→ν¯π+ using data from a combined 172.8kt·yr exposure of Super-Kamiokande-I,-II, and-III. We set lower limits on the partial lifetime for each of these modes: τn→ν¯π0>1.1×1033 years and τp→ν¯π+>3.9×1032 years at a 90% confidence level.
