Abstract
This paper reports results from a search for single and multinucleon disappearance from the O16 nucleus in water within the SNO+ detector using all of the available data. These so-called "invisible"decays do not directly deposit energy within the detector but are instead detected through their subsequent nuclear deexcitation and gamma-ray emission. New limits are given for the partial lifetimes: τ(n→inv)>9.0×1029 years, τ(p→inv)>9.6×1029 years, τ(nn→inv)>1.5×1028 years, τ(np→inv)>6.0×1028 years, and τ(pp→inv)>1.1×1029 years at 90% Bayesian credibility level (with a prior uniform in rate). All but the (nn→inv) results improve on existing limits by a factor of about 3.
