摘要：

We have searched for proton decay via p -> nu K+ using Super-Kamiokande data from April 1996 to February 2013, 260 kiloton year exposure in total. No evidence for this proton decay mode is found. A lower limit of the proton lifetime is set to tau/B(p -> nu K+) > 5.9 x 10(33) years at 90% confidence level.
