Multi-component Dark Matter from an $SU(2)D→ Z₃D× Z₂ᵃᶜᶜ$ scenario

A multi-component weakly-interacting dark matter scenario is analyzed, where the candidate dark matter states arise from the SU(2)D→ Z₃D× Z₂ᵃᶜᶜ symmetry breaking triggered by a VEV-developing scalar in the $J=3/2$ representation. While the discrete symmetries guarantee at least two stable states, a closer look at the mass orderings of the contrived dark sector reveals the existence of a third dark matter candidate, whose stability effectively results from the tight phase space in the dark boson sector. Regions of masses and couplings where the three dark states furnish a comparable contribution to the observed relic abundance are determined numerically.
