Abstract

The constraints on nucleon decay to 'invisible' modes such as n → 3v were investigated using data from the Sudbury Neutrino Observatory. The investigation was based on γ rays obtained from residual nucleus deexcitation on disappearance of either proton or neutron from 16O. An upper limit was deduced for γ ray decay greater than 90% confidence level for proton decay. This was found more stringent than previous constraints on invisible proton-decay modes.
