If Dark Matter is an electroweak gauge singlet, it cannot
interact with the standard model via these interactions, thereby requiring
the existence of so-called portal couplings. The three renormalizable
portal couplings are the Higgs portal, the vector portal, and the neutrino
portal.
In this talk, we investigate the neutrino portal to Dark Matter and
inspect the viable production mechanisms and different experimental
constraints on the resulting parameter space.
