This model extends the Standard Model by a gauge singlet scalar particle s, which plays the role of a dark matter candidate, along with an SU(2)L-singlet, SU(3)C-singlet vector-like fermion F.


The new scalar and vector-like fermion are taken to be odd under a discrete Z2 symmetry, whereas the SM is taken to be even. The scalar dark matter particle communicate with the SM through Yukawa-type interactions involving the left-handed component of the vector-like fermion and the right-handed leptons of the SM, as well as through the Higgs portal interaction.
