This paper reports results from a search for nucleon decay through invisible modes, where no visible energy is directly deposited during the decay itself, during the initial water phase of SNO+. However, such decays within the oxygen nucleus would produce an excited daughter that would subsequently deexcite, often emitting detectable gamma rays. A search for such gamma rays yields limits of 2.5×1029  y at 90% Bayesian credibility level (with a prior uniform in rate) for the partial lifetime of…

Study on Reactor Neutrino Directionality Search Utilizing Vertex Information Reconstructed by PMT Operating State in a Liquid Scintillator Detector
The properties of neutrinos are not well known because they weakly interact with surrounding matter. Recently, several interesting results and phenomena have been measured using reactor neutrinos.
Baryon-number-violating nucleon and dinucleon decays in a model with large extra dimensions
It is known that limits on baryon-violating nucleon decays do not, in general, imply corresponding suppression of $n - \bar n$ transitions. In the context of a model with fermions propagating in

Branching ratios for de-excitation processes of daughter nuclei following invisible dinucleon decays in 16O
Various theories beyond the standard model of particle physics predict the existence of baryon number violating processes resulting in nucleon decay. When occurring within an atomic nucleus, such a
Search for the invisible decay of neutrons with KamLAND.
New limits for one- and two-neutron disappearance are reported: tau(n--> inv) > 5.8 x 10(29) years and tau (nn-->Inv) > 1.4 x 10 (30) years at 90% C.L.
Constraints on nucleon decay via invisible modes from the Sudbury Neutrino Observatory.
Data from the Sudbury Neutrino Observatory have been used to constrain the lifetime for nucleon decay to "invisible" modes, such as n-->3nu, which is about an order of magnitude more stringent than previous constraints on invisible proton-decay modes and 400 timesMore stringent than similar neutron modes.
Signatures of nucleon disappearance in large underground detectors
For neutrons bound inside nuclei, baryon instability can manifest itself as a decay into undetectable particles (e.g., $\it n \to \nu \nu \bar{\nu} $), i.e., as a disappearance of a neutron from its
