The dark matter mass in this model is ${\\cal O}({\\rm GeV})$ and its relic density has a non-thermal origin. The model includes two colored scalars of ${\\cal O}({\\rm TeV})$ mass ($X_{1,2}$), and two singlet fermions that are almost degenerate in mass with the proton ($N_{1,2}$). The heavier fermion $N_2$ undergoes radiative decay to the lighter one $N_1$ that is absolutely stable.
