TL;DR: In this article, a list of particle physics models at the TeV-scale that are compatible with neutrino masses and dark matter was provided, and the conditions under which they are consistent with current data were determined.

TL;DR: In this article, a large variety of models exist in which lepton number is broken near or at the electroweak scale, including supersymmetric models with explicit or spontaneous breaking of R parity, models with Higgs triplets and pure radiative models at one-loop and two-loop order, and models in which neutrino masses are induced by leptoquark interactions.

TL;DR: In this paper, the authors examined the possibility that the dark matter candidate, N1, does not reach thermal equilibrium in the early Universe so that it behaves as a Feebly Interacting Massive Particle (FIMP), and they found that the freeze-in production of dark matter is entirely dominated by the decays of the odd scalars.

TL;DR: In this article, the authors consider the scenario in the radiative seesaw model where the dark matter particle is the lightest fermion and find that the predicted spin-independent cross section lies below the current LUX limit, although, for some choices of parameters, above the expected sensitivity of XENON1T or LZ.

TL;DR: In this paper, the authors discuss the salient features arising from the combination of the two simplified dark matter models and show that scalar coannihilations lead to an increase in the relic density which allows one to lower the bound of doublet-like fermion dark matter.
