Multipartite Interacting Scalar Dark Matter in the light of updated LUX data

We explore constraints on multipartite dark matter (DM) framework composed of singlet scalar DM interacting with the Standard Model (SM) through Higgs portal coupling. We compute relic density and direct search constraints including the updated LUX bound for two component scenario with non-zero interactions between two DM components in $\mathcal{Z}_2\times \mathcal{Z}_2^{'}$ framework in comparison with the one having $\mathcal{O}(2)$ symmetry... We point out availability of a significantly large region of parameter space of such a multipartite model with DM-DM interactions. read more
