Abstract

A multi-component weakly-interacting dark matter scenario is analyzed, where the candidate dark matter states arise from the $S U (2)_{D} \to Z_{3}^{D} \times Z_{2}^{acc}$ 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.
