We therefore augment the Standard Model (SM) with a scalar singlet ($S$) and three vectorlike fermions: two singlets ($\\chi_1,\\chi_2$) and a doublet ($N$). Stability of the two DM components is achieved by a discrete $\\mathcal{Z}_2 \\times {\\mathcal{Z}^\\prime}_2$ symmetry, under which the additional fields transform suitably.
