Loop Dominated Signals from Neutrino Portal Dark Matter
We study scenarios where loop processes give the dominant contributions to dark matter decay or annihilation despite the presence of tree-level channels. We illustrate this possibility in a specific model where dark matter is part of a hidden sector that communicates with the Standard Model sector v...
