Description
Supernova cooling has long been used to constrain physics beyond the Standard Model, typically including new mediators or dark matter particles that couple to protons or electrons. The large density of neutrinos inside supernovae also makes supernovae powerful laboratories to study non-standard neutrino interactions. In this work, we consider supernova production of dark matter that couples dominantly to neutrinos. We show that, for a wide range of unconstrained parameter space, neutrino annihilation within a supernova could copiously produce dark matter, at a large enough rate to cause noticeable anomalous cooling. We thus set novel constraints on dark matter-neutrino interactions based on the non-observation of such anomalously high cooling.
