A minimal model for two-component FIMP dark matter: A basic search / Peyman Zakeri, S. ; Mohammad Moosavi Nejad, S. ; Zakeri, Mohammadreza ; Yaser Ayazi, S.
In the multi-component configurations of dark matter phenomenology, we propose a minimal two-component configuration which is an extension of the Standard Model with only three new fields; one scalar and one fermion interact with the thermal soup through Higgs portal, mediated by the other scalar in such a way that the stabilities of dark matter candidates are made simultaneously by an explicit Z2 symmetry.
