Query: Implications of a Dark Matter-Neutrino Coupling at Hyper-Kamiokande   Dark matter and neutrinos provide the two most compelling pieces of evidence
for new physics beyond the Standard Model of Particle Physics but they are
often treated as two different sectors. In this paper, we consider how neutrino
observables can be used to constrain the parameter space of different models
where active neutrinos interact with DM via mediators of different spins. We
study for the first time the sensitivity of the Hyper-Kamiokande detector to
neutrinos produced from MeV Dark Matter annihilation. In particular, we find
that thermally produced DM candidates with masses between 15-30 MeV could be
fully excluded.
