Abstract
Neutrinos and dark matter remain two of the least known sectors of fundamental physics. What if they interact with each other? We will address this question in this talk. We implement a full catalog of constraints on the parameter space of the neutrino-dark matter/mediator couplings and masses, including bounds coming from cosmology, astrophysics, as well as new laboratory constraints from Z-boson and meson decays. As an application, we then consider galactic supernova neutrinos, identify new benchmark points that pass all the aforementioned constraints, compute the full set of cascade equations and sky maps for different dark matter density profiles in the Galaxy, and study their implications for the detection prospects in future large-volume neutrino experiments such as DUNE, Hyper-K and JUNO.
