Description
Scenarios for secluded WIMP dark matter models have been extensively studied in simplified
versions. This paper shows a complete UV realization of a secluded WIMP dark matter model
with an extra Abelian gauge symmetry that includes two-component dark matter candidates,
where the dark-matter conversion process plays a significant role in determining the relic density
in the Universe. The model generates a Dirac mass term for neutrinos and can be tested in future
direct detection experiments of dark matter. The model is also compatible with cosmological and
theoretical constraints, including the branching ratio of SM into invisible, Big Bang nucleosynthesis
restrictions, and the number of relativistic degrees of freedom in the early universe, even without
kinetic mixing.
