Search for Nucleon Decay in SNO+ light water

Data from the upcoming water-phase of the SNO+ experiment can be used to constrain the lifetime for nucleon decay to invisible modes such as $n\rightarrow\nu\bar{\nu}\nu$. The results will be an improvement on the previous SNO results due to the decreased background from solar neutrino neutral current reactions on deuterium, which are not present in the SNO+ light water. Simulations predect a sensitivity of $\tau_n > 1.25\times10^{30}$ s and $\tau_p > 1.38\times10^{30}$ s at 90% C.L. after 6 months of running, twice the proton sensitivity of KamLAND and an order of magnitude on previous SNO neutron results. Data taking for this phase of SNO+ is planned to start within the year.
