Abstract
We have searched for proton decays into a charged antilepton (, ) plus a meson (, , ) and for neutron decays into a charged antilepton (, ) plus a meson (, ) using Super-Kamiokande I-IV data, corresponding to of exposure. This measurement updates the previous published result by using 2.26 times more data and improved analysis methods. No significant evidence for nucleon decay is observed and lower limits on the partial lifetime of the nucleon are obtained. The limits range from to at 90% confidence level, depending on the decay mode.
