We consider, in a model-independent framework, the potential for observing dark matter in neutrino detectors through the interaction f p → e+ n, where f is a dark fermion. Operators of dimension six or less are considered, and constraints are placed on their coefficients using the dark matter lifetime and its decays to states which include γ rays or e+e- pairs. After these constraints are applied, there remains one operator which can possibly contribute to f p → e+ n in neutrino detectors at an observable level. We then consider the results from the Super-Kamiokande relic supernova neutrino search and find that Super-K can probe the new physics scale of this interaction up to O(100 TeV).
