     7== Model description
     8
     9In this set of three models, the Standard Model of particle physics (SM) is augmented by a gauge singlet scalar particle ''s'', which plays the role of a dark matter candidate, along with an ''SU(2),,L,,''-singlet vector-like fermion ''F''. These particles are taken to be odd under a discrete '''Z,,2,,''' symmetry, whereas the SM is taken to be even. The dark matter particles communicate with the SM through Yukawa-type interactions involving the left-handed component of the vector-like fermion and the right-handed component of the SM fermions, as well as through the Higgs portal interaction. The three models are distinguished by the ''SU(3),,c,, X U(1),,Y,,'' transformation properties of ''F'', which depend on whether the new Yukawa-type interactions involve the SM right-handed leptons, up-type quarks or down-type quarks. For more details please cf the accompanying pdf that can be found in the Attachments section.
